Hi folks,

Having a problem with "aliasing" -- little jagged edges -- in some images. Here's how: I tend to scan negs or prints at fairly high resolution cuz I like extra data/size when cleaning up dust and stuff and the high res also gives greater flexibility if I want to print later, for example. Anway to post in the galleries, I reduce these high res images in PS to 72 dpi and enter an appropriate screen size. But in photos with straight lines or especially text, these ugly jagged edges suddenly appear, even though everything else in the photo is very sharp and clear.

Is there a way to reduce large res images and avoid these jagged edges? Am I doing something wrong or is this unavoidable when resampling down a high res image?

Your wisdom and guidance is most appreciated! :) :)
