Not quite: Each image descriptor has its own Local Color Table, but the delays aren't set by the image descriptor, they're set by the Graphics Control Extension block, and you can have multiple image descriptors per GCE block. So the GIF can look something like: HDR(GCT) GCE(delay10) IMG(LCT) IMG(LCT) IMG(LCT) GCE(delay10) IMG(LCT) IMG(LCT) IMG(LCT) ..., with several image descriptors per frame, each with its own palette. However, due to historical reasons (GIFs optimized for old browsers on slow computers), modern browsers sometimes insert a small delay between image descriptors even if they're in the same frame. I generally consider this a bug. However, there are many broken GIFs out there... |
