I have Adobe Photoshop elements and do it in that but friends who send to me on dial-up experience real problems. Can you do it in Irfanview or another free program which I could get them to install? TIA TR
Dude, Photoshop is *the* best. You should be using jpeg format and you should check the resolution and dimensions depending on what the photos are to be used for. If you want to print them out in photo quality they need to be pretty big (above 150dpi and about 6" x 4"), if they're just for monitor viewing then you want 72dpi and a decent size in pixels.
Use the Image Resize feature in Photoshop and then use the Save for Web feature to see what effect the jpeg compression has. You want as little compression as possible if they're to be printed as it'll introduce artifacts.
