Hi guys,
I am in the microstock industry for 3 months now.  I am getting some downloads with not so big portfolio (average about 50 photos), but I am trying to increase it around 200 pics until the end of the year.
I was wondering how do you promote your portfolios? I mean iStock has lightboxes, 123RF has Fave images, Dreamstime offers blogs. What else are you using to promote your ports to a wider group of potential buyers?

Any info will be highly appreciated.
