Visiualizer is simple. choose a folder of photos to resize and choose a folder for the resized pictures to flow into...then pick a aspect ratio and press "resize". done what's nice is that even if the folder already has other files in there (like .doc or .avi or whatever) visualizer will just skip over it without trying to resize it and getting hung up...so you don't have to spend time cleaning out the folder first. I resized 458 photos totallying 590MB to 26MB in one batch in less than 5 minutes...now i can load all those to my on-line photogalley. You can even add a custom watermark to each photo. Great little program. one of my MVP's in an aresenal of applications.
