It was my BME. The agencies that pushed me by far up the most was Shutterstock. I had an increased of 10% compared to February and an increase of 41% compared to March 2013.

The best 4: Shutterstock, Zazzle, DepositPhotos, 123RF

(the statistic includes referral and affiliate income)

Decent month.  Up 11% from March 2013, up 23% from Feb 2014, but significantly below the peak in Sept-Jan. 

Shutterstock back to its late 2013 glory, but iStock was the worst month since July 2011 (when my port was half as large).

Nothing from Alamy, almost nothing from 123RF.

Pond5 slowly improving (3rd month, still a smallish port).

Almost identical month to Feb, and 12% better than March 2013.

SS top seller as always with 86% of revenue
DT used to make up on average 20-25% of my revenue, and now is regularly below 15% and declining (no of sales declining monthly, despite port increasing).
IS virtually non-existant, now that they're grabbing a monthly wad out of my earnings, after having claimed to have over paid me in the past due to one of their screw-ups.
The rest of the 'also-rans' are hardly worth logging onto to check on the disappointing stats.
