[Gimp-docs] Text on images

[Kolbjørn Stuestøl <kolbjoern stuestoel no>]

I am translating the eminent help articles on color management. But some 
of the (example) images has English text over the image. (Example: 
menus/image/color-management/enable-cm-gimp-built-in-perceptual-srgb-color-space-enabled-disabled.png).
Is it possible to add all text as a caption beneath or above the image 
or save a .xcf copy somewhere with the text as a separate layer possible 
to edit?
I know it is possible to translate the text on the images by 
manipulating them in GIMP, but this is time consuming.
