i see no need to get your panties in a bunch.
yes, its an embed. but its not just a jpeg embed but rather a pretty slick deviantart embed with a direct link to your gallery, a copyright notice, etc. whats the problem? worst case, youll get more exposure.

anyone who knows kindergarten HTML could embed your images from anywhere anyways - anything that is ever posted on the net is up for grabs. this controls embedding. if someone wants to make a 'best of' deviantart gallery or embed  their favorite DA images, great - more exposure for my gallery.

again, i see nothing to complain about. be happy. life is too short man.
