I have uploaded 1 image for test, at 123rf, like 7 days ago, still pending? How long does it usualy take for aproval?

Your initial submission can take up to a few weeks. After that they review pretty quick. (usually within 24hrs for me)

I can't remember how long my initial review took, but at this stage 123 is lightning fast with reviews, often just 10 minutes after I uploaded.

Chode, check and make sure your ID uploaded.  123 won't review if it isn't there.  They took about 3 weeks for me the first time last fall, so hang in there.

ID?

it says pending for that image. I just clicked save when I uploaded image (al keywords were read from IPTC data)...

Did you upload a copy of your id?  I think if you go to the uploads tab, there's a "click here" in the bottom of the grey box on the right hand side. 

Mine says "You have submitted your ID for payment verification.  To resumbit click here".

Yes! You need to upload your ID: https://www.123rf.com/submit/submit_id.php
then send a notification to them: [email protected] include your 123RF username also!
