How can I place a picture onto Microsoft Image Pro or with Infranview......and it get the properties to come out as follows:

jpeg, 72dpi, 450x350 pixels in size, 59k

When I try with Microsoft Image Pro ( I set the pixels to 450x350) it automatically resizes the picture to 450 x 335 and results in a size of 14.8 kb

I know it can be done with a MAC (adobe photoshop) , but I have a PC. I have Publisher, Image Pro, and Infranview. SHouldn't one of these work?

*I need the image resized to fit into a revolving flash on a website. So, it has to be exactly the size I mentioned above.

OK, There is Adobe Photoshop for the PC, but You can do this with almost any program. You can re-resize the picture back to what it needs to be if the program shrinks or enlarges it automatically. Mostly size is depedant on the File Format of the image, and the quality of the image.

Is there any Specific File Format?

Edit: Sorry, just realized it needed to be Jpeg. But its mainly quality your worried about then

You should be able to go to Edit or Image in Irfanview and there should be a setting about image size.

I bet someone who uses Irfanview will come along and give more specific instructions soon.

Yes you can do it in Photoshop via the save for web ~ optimise to file size feature.

In the rest, I imagine that you will just have to keep saving the file at different compression levels until you get as close as you can.

Of course all these methods (even Photoshop) can only get you close - usually to within 1 kb.

About the pixel size: ------------------
When you use IrfanView, typically when you resize, the adjustment will keep the proportions, so as not to distort.
For example, if you have an image 1000 pixels x 1000 pixels (it is square) and that you need the resized result to be 500 x 550, then any time you adjust one of the sides to be 500 then the other side will be forced to be also 500. OR if you select a side to be 550, then again the other side will automatically be 550. All that because IrfanView (as most other graphic editors) will try to maintain the square.

UNLESS - in IrfanView, you UNSELECT the "Preserve aspect ratio"
Doing that, then you can resize to any dis-proportions you want.

About the DPI setting: ---------------------------
That is just a setting, perhaps used by a printing program to print an image to some dimensions. A DPI setting does nothing for a web image, since most web images will either show at a 1 image pixel to 1 screen pixel ration - or, perhaps to some webpage set image size dimensions.
You can adjust the DPI with IrfanView - if you really need any particular DPI.
Changing the DPI up or down will not affect the final image file size more than a byte or two.
(I have a series of identical complex images - identical in all aspects except for the DPI. The user can't detect any visible difference, because there isn't any - however the DPI difference goes from 2 DPI to 1000 DPI.)

About the file size: ------------------
The end result of any image will depend upon the desired pixel size, compression scheme, the image complexity, and the number of colors. The file size is a result, not so much that you can say I want the result to be "x number of k bytes."

You said you want the JPG format, so that more or less sets your compression scheme - however IrfanView does allow you to lower the image quality (being more lossy) if the end result is too large in the number of bytes.

Since you want the output to be a JPG, even lowering the color quantities (color depth) does almost nothing to reduce the file size.
Now, if you have fewer than 256 colors in the image, you might consider making the image a GIF, which might be more compact than JPG. And GIF is a well supported image type for all browsers.
If you have more, and need, than 256 colors, then you might consider using PNG format, but PNG support is not in all browsers yet.

------------------ So, if you do stay with JPG
If you make you image the size you want, and the file size is larger than you want, then just the JPEG "Save quality" downward and see if the new saved image is good enough, and small enough, for you.

Good luck.

Getting the exact pixel size 450x350 might be a little tough in Irfanview.
Using Photoshop will be much easier.
To get the file size exactly 59k will be next to impossible ... going to need a range here.

Might be easier to get us the picture .. and one of us can do it in Photoshop.

58.1KB is as close as I could get in this test photo ...

I can give you instructions for cropping it to the right proportions in Irfanview, but it would probably be easier in Image Pro. It has pre-set and custom crop selections. You want to go to custom and crop it to 4.5 X 3.5 inches. Then it will give you the right width and height when you downsize it. Ignore the PPI.

The save dialog might be a little better in Image Pro as well. Most editors tell you what size the jpg will be at the selected compression but Irfanview doesn’t. Just select jpg quality until it is around your desired 56k if Image Pro gives resulting file size.

To get 56k from a 450 X 350 image with Irfanview you use about 85%. Every jpg compresses differently according to content, but that is a starting point if Image Pro doesn’t just tell you before the save.

If you want to do the whole thing in Irfanview you sort of back into the result. Go Image > Resize/Resample. Check “Preserve aspect ratio” and put 350 pixels in the width. Take whatever it gives you for height – it should be over 450 pixels. Make sure the method is set to Lanczos and OK.

Edit > Create custom crop selection. Check “None” for ratio and put 450 pixels in the width and 350 in the height. Apply to image. Move the selection with the right mouse button – you will be able to go only up and down a little. Edit > Crop selection.

The alternative is to just distort the image a little with ChuckE’s instructions. The only reason I give you the crop instructions to keep the image proportions is because NOYB brought it up.

File > Save as. Name it and select jpg and a destination. Set your slider to 85% and uncheck everything if you don’t want to send EXIF, comments etc. My test image gave exactly 56k at 85% but it varies with the image.

Here is the photo that I was given as an example. I just need to know how to get this exact size for future pictures. This picture was done on a MAC which I don't have.

[ferrija1]

Here it is (attachments).

Since it sounds like you have to do this again, I'll tell you how to do it in an easy program called Paint.NET.
http://www.getpaint.net/index2.html

1. Once you have downloaded and installed it, open the image with it.

2. Go to Image > Resize and change it to the size you would like it to be.

3. File > Save As...

4. Choose JPEG

5. Change the quality until it is the right size (see attachments).

This example picture is already 450x350, there is no need to adjust the size at all.
The file size is already just 29k, which is smaller than the 59k (you showed , so are you guessing for a max size?).
The only other thing to set was the DPI setting, so I did that and giving it back to you here.

Here are 3 images in the attached zip:
"clip72" is your original, just with the DPI set to 72, which for a web page doesn't do anything for you, but here it is anyway.
"clip7299" which "fattened" up the file size to about 58k (why do you need that larger file size?). I made this fatter by just adjusting the Save quality to "99" (IrfanView's slider control) and
"clip7253" which I only made as a test, to show you can make the output any size you want, without regard to aspect ratio, so I decided to adjust the image to 500x300 pixels. I just picked those numbers out of the air, one bigger than what you had, the other smaller. There is NO difficulty in making an image any exact pixel dimensions you tell IrfanView to do. (I have no idea why Noyb said it "might be a little tough." ??)

It really strikes me as odd, if you really need a picture to be 59k. I can understand someone specifying a "no more than 59k" but not a "final file size must be 59k." I think some of the people here may be reading more into what you said than needing.
BUT! if you really, really need a final size of exactly some number of bytes, I know I can add some metadata to the file that will tweak the file size upward to whatever number of bytes, right to the exact number of bytes ... if you want. It won't hurt your image, but it really is an odd request.

Yes, but just in case the picture is too big or small sometime.

No, the original is 78 KB.

The "original" posted in msg#8 is what I was working with, but my browser saved it as just 29k. Then, when I just tried again, seconds ago, it is now 79k, go figure.

Be that as it may, here then are 5 versions of the same 79k 450x350 image using various "Save quality" values. Using quality values from 80 (my typical setting) to 90 (those values are only relative to using IrfanView, as I do. Your image editor may use different values or even a different scale). The result files are from 53k to 61k, with a value of 88 resulting in a 59k file size.

.

I know that the example picture is exactly the right size. I will need to resize another picture in the future to replace it and thats where I'm having the sizing issues. Take any picture you have and try getting those exact dimensions.........its almost impossible without using a MAC.

[ChuckE]

It is not impossible at all. I can take any picture and resize it to 450x350. IrfanView works fine. Just follow the instructions already mentioned above.

I have taken a 1 pixel (1x1) and a 1000x2000 pixel image, and resized both to be 450x350. How are you having problems?

OK, take the attached picture and tell me if you can do it. I try with Infranview and when I put the 450 in thats ok, but it changes the 350 to 354 every time. ( I'm clicking image, then resize, then set new size and then inserting the exact hxw) How would you do it? And can you get the size to be 59k when you are done?
