I am very new to PS, i have several pictures to use on my site....but they are in thumbnail size, i need these to be something like 800 x 600 wallpaper size images, but when i do that...well the images turns out looking really bad. I know that there has to be a way to get this to work. I need those images that are like 1.5 inches x 2.3 inches to be up to 800 x 600 pixels, but without losing any(or very little) quality. If there is an easier way to do it without PS..let me know
