ASCII Artist / Text Files and Image Files for ASCII Art

I have my ASCII art posted as text files but I'm hesitant to provide the link. Too much ASCII art is stolen, far too easily and it is very hard to discover stolen art and even harder to do much about it. I am looking for a way to post it with less risk. My first option died, Web eCards. I paid for the software but it has stopped working and even the website is down now.

I liked the idea of making ASCII art postcards people could send to each other. I would have been able to make the image files with a watermark, of some sort, to keep my artist initials and website link on the image file. Until I find something like that, simple to use and figure out, the text files are not available for the public. But, I will begin posting image files here again.
