I'd suggest to use a lookup table in the Theme file (/horde/config/themes)
to
override the default image names.  So instead of calling

img("myimg.gif", _("My Image));

this could be used:

img($theme['myimg.gif'], _("My Image));

or even

img($theme['myimg'], _("My Image));

(using a default lookup table called before the theme file is read, of
course, so the theme only has to override the necessary filenames).

as 8-bit indexed PNG can be a drop-in replacement for GIFs _without_ any
AlphaGizmoMicrosoftCall/Script (there's only a on/off transparency, but
that's what we have with GIF anyway), a naming convention could be used
for truecolor alpha PNG images; prefixing images with "a_", like in
"a_img.png" might be used to wakeup the IE-scripting calls in img();
