Has someone been trying to hack the forum signature processing? If so, it's now hosed. I put an image sig in my profile today (only 22KB). When previewing a message it shows up, but after submitting the message it does not. Strangely enough, my old messages with a text sig now do show the image.

(Image above is included in the message. If there is not a copy of it below, signature handling is screwed.)
