Welcome to Retouch Pro! If you have any version of Photoshop, just go File>Automate>Picture Package. A dialog box will come up and you direct
PS to a folder containing your photos. You define how many photos you want on what size page (for example 8x10). You tell it the quality and whether or not you want image names etc. Then
PS will sequence through your folder and do its thing. If you have 1600 photos and you want 10 photos per page, the
PS will build you 160 pages or asmany as it takes to process the number of photos in your folder. These pages can be saves as standard jpgs and later printed.
