I think the problem with DJzen's sig was that it was a bitmap, although it was named as .JPG. When I tried to save it, it would only let me save as a .bmp, and it said it wasn't a valid JPG file.
Anyway I saved it as a JPG, and the size is now 21k, so you're okay.
Thought I might as well fix it back in your sig too for you while I was at it, so there you go
