So I'm thinking about uploading images there and placing url links to this thread and your accounts (only if desired).
Everything there is Creative Common License and Free. I will not declare one single picture as mine. Everything is for the purpose of sharing and linking to this thread.
If there are any concerns, I'll just leave it.

No concerns from my side...
But I have to emphasize that I did not created a single picture myself. I only used the finished png's from websources (also from DeviantArt), i only cut/resized/compressed and sometimes used the eraser.
There are also many paste/copy duplicates on DeviantArt. As long as you declare no pictures as yours, politely formulate the description text below the pictures and what it is intended for, i really see no problem here.
