Sorry Cynthia, border may not have been the clearest way of presenting the diamensions of the canvas, I meant the outside border/ height x width.
I have been searching the Adobe archives for responses to this topic. For image software I use Adobe Photoshop, Image Ready, Illustrator for vector. Let me see what I can find from someone more articulate than I....

If you have a picture 25" x 16.667" @ 72dpi(1800px x 1200px), you can change the res to 300dpi and keep the pixels at 1800 x 1200 and you'll have a print size of 6" x 4" with no distortion.

The first thing we need to look at here are the relative sizes of height: width of the "Before" and "After" images.
1.5" X 3" cannot be successfully enlarged to 5" X 8" without introducing some spatial distortion. Since you'll be limited to 5" X 8", you'll need to expand the long dimension to 8" (that's a multiplication factor of 2.667X)...multiply 1.5" by that same factor, and you get 4". Sooooo....you'll have to deal with an inch of blank space. This could be along one edge of the card or split between both edges. You'll have to decide what you want to do with this blank space.
Next, if you change the dimensions of the image without resampling you'll end up at a resolution of 187.5 pixels per inch. Depending on the actual content of your image, this may be sufficient. If not, you can certainly raise the resolution, but in reality what you'll be asking Photoshop to do is to "guess" how to fill in image data that is not present in your original image. Again, depending on the content of the image, this can work well, or it can be disastrous.

Great image explainations and tips
I even learned something new here, I usually save my high res as EPS, Tiff is the better option.
[QUOTE]When I open a JPEG photo taken with my digital camera in Photoshop 7, the original file size might be for example 350kb. But, when saving it (as a JPEG) and using the maximum quality setting/least compression option, the resultant file size would be around 700kb. Does anyone know why please? Am I right in thinking that the original file from the camera is compressed, whereas after I open it in Photoshop and save it, I am saving the uncompressed version.
Your thinking is correct. Photoshop decompresses the image when you open it. If you saved the image at the same quality that your camera did you would end up with the same size file. Saving at best quality just doesn
