If few people are looking at my streams, then I can only assume few people are troubled by what I do with them.
If you really want to know: I upload a pic, click the checkmark to mark it as a template, and then when the generate meme page pops up I typically go ahead and toss it on the Kylie Stream right then and there, because why not.
I typically add a title as well. But no, I don't feel the need to caption most of them.
Whenever this process produces something I really like and that I think other memers might get use out of, then I repost in the
imgflip.com/m/My_Custom_Templates stream, like this one I've gotten a lot of mileage out of already
