Right, the problem is getting the data *into* the pixbuf in the first
place. Basically I have the image in a long string in memory and need
to get that into the Pixbuf somehow. The pixel_array is read-only, so
I can't use that.

I don't think Gustav's idea will work because the loader expects the
*encoded* pixels (+ header, etc) from a jpeg file, and if I already
had a jpeg encoder I could just save the file myself.
 
Thanks,
