Alamdari,

How "big" are the picture files that you're talking about. I've found that a relatively small picture file, say a jpg of 10-50 KB is sufficient for good definition on an internet page. Even a full screen picture is displayed fine if it's in the 75 kb size range or less. Larger picture files tend to get compressed on pages so they are distorted. Keep the picture sizes to something small and they'll load faster and look better.

Hope this helps.
