Just thought I would shre with you.
Everyone may already know this but maybe they dont.
I have recently been developing some flash software demonstrations for my company and I noticed a funny thing with screen shots. Even though the screen shots looked perfect in PS when they were displayed in a browser they looked sh*t.
I finally realised that it was because the image displayed in the browser was actually a different size to what was in the html and flash. This is due to the flsh being resised in the html.
The solution was to do a screen shot of the html while being viewed in a browser then saving the image to the same size (pixel wise) in PS and importing it into flash.
Result was perfect screen shots.
Hope this helps somebody.
