Just trying a batch in a folder of png files, want to convert from indexed mode

using Xubuntu 14.04 if that makes any difference).

I tried this and got an error:

gimp -i -b '(gimp-image-convert-rgb "*.png")' -b '(gimp-quit 0)'
batch command experienced an execution error:
Error: ( : 1) Invalid type for argument 1 to gimp-image-convert-rgb

Can anyone explain to me what I did wrong?

The first parameter to that function is an image already loaded in Gimp, not a filename (with a wildcard too boot). So your script would need to iterate the wildcard pattern, and for each file, load the image, convert it, and save the result.

But for this kind of work, you should really be using the ImageMagick toolbox (available in the Ubuntu repositories), a set a command line tools to edit/convert images. See
