For example this strategy should work: 1) select the background layer (usually the lowest one in the layer list) 2) choose the "select by color" tool 3) set the tool parameters to the following a) deselect all checkboxes (e.g. no smoothing) b) set the treshold to zero c) set the mode to "replace current selection" 4) select a background color pixel with the mouse 5) invert the selection (e.g. CTRL-i on Windows/Linux or CMD-i on a Mac) 6) copy and paste the selection as a new layer (e.g. CTRL-c CTRL-v or CMD-c CMD-v, then click on "new layer" to settle the floating selection as a new layer) 7) move the pasted layer to the bottom 8) delete the original background layer It might be necessary to repeat this for other layers also containing the background color you want to make transparent. Before doing this the image should already be in "indexed" mode. This should be the case if you already have an animated gif. Otherwise you must change the mode first.
