Hi all,
When uploading pictures, does the file size of jpegs determine how large the receiver can view the picture? Can the receiver enlarge the picture on their end. Most info tell me that jpegs with 72 dpi are best for internet viewing, but they are small images.
Thanks

Yes they can but depending on the size of the pic you send, results will vary. If you make the pic small, and he or she tries to enlarge it it will most likely look terrible.

You can go to a site, such as http://imageshack.us/ and upload your photos to it. Then you copy a link they provide, and send only the link, to email, forums or whatever. It will show as a thumbnail in forums, and open a larger image when clicking on it. You can upload up to 1024kb per image.

How large you can view the image and still have it sharp is dependent on the pixels in the image and not on the PPI. Right click on the image and select “Properties” for an image online. If the image is 400 pixels wide and 300 pixels high it will fill about half of the width and height of a screen if someone has their resolution set to 600 X 800. If the resolution is set higher it will fill less of the screen.

If it is on your computer, View>Details will give you the size in kb. If you open it in a viewer there is usually a way to determine the actual size in pixels. If you computer is defaulted to open the image in Internet Explorer you can right click on the image and select “properties” to get the size just like an online image. You can right click the image and select “Open With” to open it in Windows Explorer.

More sophisticated viewers like the free Irfanview can be set to view it actual size in pixels or fill the window. It is under View>Display Options. You can see the size in Irfanview by going Image>Information. If you want to see what it looks like large you can set Irfanview to View>Display Options>Fit Image to Window. Make sure the window is full screen. www.irfanview.com if you don’t already have it.

If the image is only something like 100 X 150 pixels it won’t look too good when made to fill the window. Images smaller than about 300 X 400 look pretty bad when shown full screen.
