Do you know of a good tutorial on how to SEO image contents, i.e. jpg photos?
A funny story: I do very solid, simple websites in full compliance with the Google webmaster guidelines and other simple SEO rules. Nothing special, built up with lots of advice and learning from WW and other sources.
I have a friend who works on many websites with related contents. We compete for high ranks at the SERPs, sometimes I win, sometimes he does.
The only big exception are photos - he scores fabulously at Google image search, wherewas I just cannot get my pictures rank well at all. They are often of much better quality than his. We have discussed this among the two of us, and have no clue what he does differently.
Perhaps you have any clues?
