when u reduce it down in stretch/skew i put in 25 in both boxes and that gets the pic down to the right pixels needed to post, now you dont have to play with it to get it right
I use a program called irfanview.
I load imange into it, then I go to image at the top,then go to resize/resample. I can adjust how many pixels I want.
I use a program called Microsoft Office Picture Manager were you can resize to website size. It comes with Microsoft Office 2003, I think. Or it comes by itself. One or the other.
