My question is, if those people, who decides, if an images ends up in a galerie, or if it is archived, know (see) who posted that image. Thanks for your answers.

They don't have to know, but they very easily could.

Do you know? Yes, if they would not know, they could go and look through the galeries ... but I would like to know, when they look through the images and do their thumbs up or down ... if they know, who posted that image... But thanks for taking the time to answer.

Images are moved based on content not the artist who created it.

Mods are able to see the artist names as well as all the other details that every other member can see.

Moving and archiving are so big jobs that we don't often take the time to look at artist names...

Thank you all for your answers. I still worry, that one of you might be influenced by the name (without knowing it) and that a blind testing would be better (like you would do it, when you taste drinks or food), but again, thanks for taking the time to answer.

It's funny to know that sometimes, we can recognize the style wihout seeing the artist name. That's often the case with the members who were nominated in the Artist Spotlight :-)
