I'm not realy into editing lot's of family pictures or anything on my computer. The main thing I mess with is downloading and saving cool Star Trek pics in JPEG along with some cartoons etc. Having said that the biggest problem I have is understanding dimensions. For example I have one pic that is 2560 X 1920. How do you figure out what that would be in inches? And is there a utility that shows you how to convert that or something? Also so you know of any good programs that allows you to resize in inches?. Adobe Photoshop came with my computer but that is way to complicated for me. I'm looking for something more simple.

Pixel dimension and DPI (dots per inch) relates to printing only. For monitor display or video only the pixel dimensions have any relevance.

For example,
An image of dimensions, 2560 X 1920, printed at 300 DPI (300 is a baseline resolution for printing - a higher resolution would be used for, eg: high quality art prints, and a lower resolution for large print jobs eg: billboards) would have 300 pixels for one inch of the printed image.
It would give a printed image approx 8.5 by 6.4 inches - 2560÷300 = 8.5 (inches), 1920÷300 = 6.4 (inches).

As for Photoshop, You could try Photoshop Elements (a stripped down, user-friendly version), or maybe Paint Shop Pro, once again a good medium level prog.

For An excellent free Imageviewer and simple editor (cropping, resizing etc) you might want to try Irfanview.

The freeware Irfan that lister links, will show you resize calibrations in: Pixels, cm, inches.
Load an image into Irfan and click Image->Resize/Resample.

All the previous editors will work just fine for you.

As you already have photoshop, why not open the image in that program and then go to

image>image size.

This will tell you what size canvas is considered correct for the pixel size of the image and the resolution of that image.

As lister has hinted, it all depends on the resolution of the image.

When Lister suggested 300dpi, this is really the minimum benchmark for getting into a decent result. If your image is showing less than that, I would suggest that you change the pixel count (not hard) to at least 300dpi, retaining the pixel dimensions and then see what size is then given, remembering that most images dragged off the web will be at 72dpi.

PS Do this on a copy of the image so that the original is still intact.

At least it will give you an idea.
