Just click sell only and you can upload the max. amount of images for sale.

The PC thing is photocommunity in addition to selling images, take part in forum discussion photo competitions etc. By clicking this you can upload images to the Photocommunity so people can rate them and tell you how great your image is.
If you want that I would recommend PC Standard, because its free 

Pros: - you can make a lot more with one sale than on the micros
-you are paid in Euros
- they even offer banktransfer
- you can already request payout when you reach 30 Euro

Cons:
 -not as many sales
- 30% royalty when you offer images at cheaper agencies
- sales are sometimes not as predictable (For a few month they beat even Fotolia). But lately they are tend to be more in the income range between 123rf and StockXpert
- inconvenient upload system

Cons:
 
- inconvenient upload system

Freezingpictures, this seems to plagued the more recent  sites, don't they?
eg moodboard, zymmetrical, to name a couple

Pantehrmedia is not that recent, they are pretty established in Germany. It was actually my first stock agency I submited to in 2005. But they went international less then 2 years ago.
