Firstly...........is it possible to download high res photos for free anywhere? I've googled it a few times but not been able to find the subjects that I want without paying for them. Incidently on eBay, various sellers have individual shots for sale but they are quite expensive. Where do they get them from? For example Moto GP pictures (without any watermarks). Most of the CD, DVD collections for sale on sBay are for 'Babes' but I very much doubt the res will be good enough to print decent photos up to A4 size.
Secondly....what res is needed for a high quality 9x6 and A4 size photo?
Any help would be welcomed. (All photos are for personal use and not for resale).
