What to sell with Image NIche?

Can anybody help me wtih this? I am having problem on
what to sell on this niche. Or anything that would earn using
this Niche.

Thanks,

Seems no one is this business.. Anyway, i was researching and has find out
that you can actually advertise images from istockphotos (affiliate).. other
sites selling images. hmmm... but still i have doubts if i can make this
work... waaaaaaaaaaaaaaaaa... need help!

i think i will be alone in this method! lol

You can promote some picture editing software !

What image niche? That's just too broad a question.
