800x600x365 Animated GIF - Any Better Way?

Hi,

I have a series of maps for each day of a complete year, each map being around 800x600. The map itself doesn't change at all, but each one has its own version of the colour table, customized for the specific day. I manipulate the colour table through VBA in Excel, leaving the first 13 bytes and bytes 781 to the end unchanged.

I'd like to put them together into a single animation, but I'm running into problems. Firstly, the file selector won't let me choose 365 files at once, so building the file list is a pain (would be nice if it didn't flip the positions of first and last files selected!) - but the bigger problem is that it won't finish. It sucks around 450Mbytes of memory, takes an age to assemble the GIF, and after all that, can't save it. And doesn't give me back all my memory.

There HAS to be a better way, but I suspect it's going to mean building the finished GIF in VB.

Any suggestions, anyone? Failing that, anyone know where I can find the necessary info for building it myself?

What if you built say 100 frames at once....then you could combine them into one project when your done. Just a suggestion.

Hmm, hadn't thought of that. I'll give it a go, thanks, and let you know how it works out. Otherwise, it may be easier to try to handle the whol thing in VB, pass in a single gif image and an array of replacement palettes, see if I can't just display them directly out of memory.
