any tumblr users here know if its possible to contact tumblr about having images deleted?

I posed some ahem. impolite pictures of myself, a couple days ago, and then realized today "hmm hey maybe having these kinda things all over the internet is a bad idea" so I deleted them from my own blog but not before some random user had reblogged them. i guess when someone else reblogs, even if you delete the original post it still shows up on their tumblr for some reason.

do you think i would be able to contact tumblr support and have the images removed entirely from their database, since they're both hosted on tumblr.com? has anyone ever had to do something like that before, or even just had good luck with tumblr support? xD god this is an awkward question but i'm not sure where else to ask honestly.
