photoshop can definitely resize your photos. Sometimes there are easier free utilities if you're not too familiar with photoshop. to do this on a single photo, with the photo open, go IMAGE>Image size and enter your picture dimensions in the second set of boxes. It will keep the proportions constrained as long as the chain link is complete, and you'll only have to enter one dimension for it to do both. Doing a batch process of many photos requires an action to be recorded and then using the AUtomate>Batch command in photoshop or Bridge (CS2/3). This is a bit clumsier for the new photoshop user. Search for "photo resize" on versiontracker.com and there are a number of freeware photo batch resize options. hope this helps
