For microstock, start with the top 8 in the list to the right.

Shuterstock is my highest earner, here's my referral link

For footage, start with Pond5, Revostock, shutterstock and istock

My Pond5 referral is

I also recommend alamy for higher priced images.

if not spam then certainly a weird post in a forum about stock sites...

well micros are on the right, go back to the main forum page and down bit and you get info about them, and then you'll find illustrations, video & macro sites too

in amongst the wads of info on the forum is threads like were else should I submit & what other sites other than alamy.

I blogged my impression of three stock footage sites:

GREAT blogs - plenty of info for anyone trying to enter this new area.    -- i've been submitting t SS, pond, revo, motionclips for about 2 months now -- no sales as yet, so no comparisions possible.  for acceptance, i've found pond takes 90%+ while SS is about 60-70% and revo about 1/2 -- but many revo rejcts can be resubmitted and the reviewers have been extremely helpful in bothintitial review [specific suggestions for how to fix the clip] and for followyps

i'm considering submitting to canstock & zym also -- any ideas?  [i'll get arund to istock eventually but their submission process requires multiple conversions and upl's, and their performance in MS is minimal.
