There’s a distinction tha needs to be made here. The compression of a photo
is not as important as the overall size of the photo.

I disagree a smaller file size is far more important to me than resolution
size.

I have to work with printing, so I’m resolution-biased:)

I use Photoshop as well so... When you save as a 640x480 jpeg using a
compression of 5, it usually makes the file size 50-80k depending on how
busy the picture is. However when using a compression of 10 it makes an
image 200-300k with very little (if any noticable) gain in picture quality.
Personally I would consider a 640x480 image in the 50-80k range “optimal
viewing”. If it is impossible to keep the resolution size 640x480 then try
to make the file size as small as possible.

That is something that is dependent on the complexity of the image. Large areas
of color can be compressed without a problem, but if you have a complex pattern,
you could have rastering probs. Lego photos tend to be in the middle of that
spectrum, with broad areas and small stud textures. My compression setting is
at 8. I try to keep my graphic size at 7 or so inches wide

Okay...so where is the command where you can change the compression from 10
to 5??
|
When you save a file as a JPEG, you should get a window that gives you a slider
to change compression level. That’s where you change the settings.
