Just wondering if bigstock is worth joining? well?

Big Stock is a slow moving image bank. It does sell. I have about 411 Images up there and granted... some are not my best.
Here is my stats
Frans Bigstock Earnings
411 Sales $ Sales/$PD
July 5 2.50
Aug 18 9.00
Sept 34 17.00
Oct 37 18.50
Nov 12 6.00 0.67
Total Sales 106 $ 53.00
The sales are increasing month on month.
So I'm making about 0.67cents per day on Bigstock. I must add that I only had about 400 Images up there from mid Oct. It is picking up. I know Forgiss is doing well there. He is avaraging about $10 per day there BUT has about 1200 Images uploaded.
Bottom line is if you have the time to upload to them... Go for it. I actualy upload to a few image banks on the same day. Just time .... and you will make sales but it is slow. I know Milzo has stopped uploading to them.
I believe Johan site is not a bad idee. The feel is easy and if the marketing is done well, it WILL boom. The question remains: Are you on the ship when it sales or are you still trying to jump onboard. I will atleast have also a site in UK.
