It's actually pretty easy and I just realized it last night lmao.
Basically all you need to do is upload a reeeally tiny transparent box (there's one here if you want to just download/reupload it), and make it a featured deviation on your page.
Once you do that, you can edit the description and add in an < img src=""> tag, putting the url of your image in the quotes. (Don't use a space at the beginning of the tag lol)
The result looks something like this!
So screw you for taking webcams out, dA! We can make our own! D:< //shot
