This is even easier, because jpg's ignore additional data past the end of the file. Post a low-res ~200kb jpg that has an additional ~20mb of data appended. It'll still render perfectly fine.

The other consideration is that Tumblr was always very “creator” oriented and while they might produce thumbnails of various sizes the original image is still available and not mangled by resizing algorithms. Other free image hosts are going to crush that image down the maximum amount tolerable to the human eye. Google even does that for paid photo hosting.
