What is a good method/software for reducing file sizes and retaining a good quality. I would like to modify my pics to fill a normal window in Pbase without scrolling and keep them at a minimal size. I see great looking full size pics in galleries yet still under 100 MB. I use photoshop for editing and have also tried ACDSee for resizing.
If you have to do a lot of pictures at one time, look for the free program IrfanView. I'll do that when I want to get a lot of pics online for others to view in a hurry. It will batch process all the photos, resizing and altering the quality accordingly.
Otherwise, as another poster indicated, you want to downsize to about 800x600 (or 800x533 if you are using a 3:2 format camera, such as most DSLRs). When I manually downsize in Photoshop Elements, I use a target quality of 9, which is still very good quality for web use.
Looking at the stats on my own gallery, where I post most everything either 800xWhatever or 640xWhatever, my average image size is 156 KB.
