I have Photoshop versions 4, 5 & CS and hardly use them , I know there the industry standard but they can be over complicated for general use like re-sizing etc .I have always used Paint Shop Pro , dead easy to use , my version is only about 9mb , so dos,nt take up loads of space and dos'nt take ages to load. If I have pictures to crop or re-size , say for e-bay , the quickness of PSP comes in very handy .
I once loaded 1500 plugins for CS to try out and the damn program took about 5mins to load and that was on a 2gig processor laptop .Quickly got rid of them .I do think Photoshop is worth having for some things , but ,I'll still stick with my PSP thank you .
