TPF Noob!
'Resolution' as such (300ppi for example), will have no impact at all, except telling a printer what size it is 'programmed' to be printed at a certain number of pixels per inch.
All that matters is the actual size in pixels - I always keep mine below 600pixels on the longest side - at 300ppi it will print at 2 inches, at 150ppi it will print at 4 inches, at 75ppi it will print at 6 inches but will look like cr*p
Very true. Dont put a large size on your website.
Web images can only be at 72 when you print at 300.
