Working on the scratching an itch principle, my EOG will now check a JPEG image to see if it contains any embedded white point and primary colour coefficients. If it does, a ICC profile is generated from the data (using a gamma of 2.2) and the image transformed to sRGB. It's a little slow at the moment as I'm doing it row at a time, and it has a habit of crashing on the last row but one (no idea why), but if I tell it to transform only half of the image the results are impressive:

The next stage once the bugs are fixed is to make the code optional, and to handle embedded ICC profiles.
