This question seems to have been asked a number of times but either the requirements are different or I'm not able to follow the answers.
I have an animated GIF that was created using a third party tool. This tool uses solid green (#00ff00) as the colour to represent transparency.
This GIF needs editing as it needs breaking down into different sections to produce multiple smaller GIFs, I'm doing this in Photoshop CS5.
However I can't seem to replace the green with transparency, when I export the GIF from CS5 the green is there as a solid colour.
So what Im asking is:
Is there anyway to tell the "Save to Web" tool that #00ff00 should be transparent, OR
How can I delete the colour from all of the layers (there are 591 of them), OR
Is there anyway I can use a mask to make that colour transparent?
