How to find all/any copies of an image on the web?

I have a jpg file. What is the best way to find any instances of this file posted anywhere on the web. This is pretty much a dupe of this AskMe from 2004
but i was hoping technology might have advanced enough to provide a new answer.

I realize it would be very difficult to find resized versions of the file. But finding exact copies, albeit with differing file names, seems technologically feasible.
Surely it would be easy for google/yahoo/whoever to calculate some hash of each image in the database, which would then allow me to calculate the same hash on my file, then search by that hash? Does anyone know of a site that allows this? I am a programmer, so would not shy away from using an API rather than a nice gui interface.
Failing that, I don't understand why no one will let me search for images by size. And I mean exact pixel size, not the vague (small, medium, large and extra large) categories that all the search sites have now.
The answer to 'why would i want to do this anyway' is that someone has posted a nsfw image of a friend of mine to the web. I don't know the original place it was posted, but I do have a copy that someone reposted to a forum. I would like to search out any other copies, and would be even happier if in doing so I find out who originally released it into the internets against her wishes. The reposter has taken the pic down and 'thinks' they got it from imagevenue or some site like that, so any solutions specific to imagevenue would also be potentially helpful.
As always, thanks to everyone who answers.
