You can take a chibi or sprite image, layer it over part of the image, and change the opacity so it can be linked back to you. I do this on Deviantart as I know it's easy to find images when using it.

Ouch. I’m so sorry to hear that.

This honestly infuriates me. "Will take down upon request". So, the art owner has to comb the internet in search of art thieves, just to maintain the reputation of their characters. Fantastic.

As someone who runs one of those art dump channels i completely understand why you're frustrated. I always link to the original FA/e621 post i found the art in, and it frustrates me the most when i see people dumping good art in their channels with no credit what so ever! (and terrible compression too)

I sent one of my friends your art because he likes it but i wish i could send him your entire gallery iwi

Will you publish all your gallery again?

If I can get around to it, possibly. I am admittedly lacking in the motivation required to do so.

That is a little sad to be honest since I really like your art and characters. I really hope that you figure something out but if you don’t then at the very least it was fun while it lasted and I don’t blame at all for choosing to keeping it to yourself. After all no one wants to get robbed

aww... i really liked all your stuff, this is sad

Really loved your art gallery, so sad about the problem with thefts, sadly on internet there is no control over it and art will end on others hands, it's sad but the community will always recognize the original source. Keep up!
