I was having trouble with image quality, so I searched around for the quality solution and found the answer. Then I tried to share the answer with others to pass on the help. Somehow, during the process, I found your posting.
I almost gave up on 4images. I have been using Gallery 1.33 and it has been great, with only one exception that it does not have an attractive user interface. I also like that you can click on the set size of the picture and get the original size so that the user can download the best quality picture. If 4images can do this, it would definitly beat Gallery for my purpose. So far, I am still using Gallery and watching 4Images.
BTW, another benefit of ImageMagick is the smaller files size, comparing to Netpbm and GD. Yes, I am also wantering why, they chose '-sample' as the default setting. That might have driven quite a lot of people from 4Images, like I almost did, because I use ImageMagick.
