UPDATE 9/13: I’ve fixed the bug and will be releasing the fixed version sometime tomorrow.

There is a bug in Facelift that is causing all images to be generated with a white background. The temporary fix is to disable GIF/JPG support until I can release a fixed version. You only have to modify one line of code to fix and FLIR will behave as it did before with transparent PNG images.

You can read more about the problem and get the fix here.
