Using the built-in generator changes the color of the background color under Chrome, yet using my own blank doesn't cause this. I've attached a "known good" blank created in Fireworks (same byte size) so it can replace the one in the nginx codebase. I am under windows with no development tools so I can't create a patch myself but I'm able to test a new binary to validate that it's fixed.

The current empty GIF has 2 colors: #0: black and #1 white. The white (#1) color is used as background and as transparent color.

The suggested GIF has two colors: #0 gray (C0C0C0) and #1 black. The transparent color is #0 (gray). The background color is #256

The background color is #255 ...

and there is no such color number in the GIF table. I'm not sure how browsers will handle this case. Probably they use just #1 color.

However, I do not understand the issue. Could you show example on the web where built-in GIF changes background color ?
