All the files that are RGBS and not named as tm_xxx are actually only 
used on the website to serve as links for next pages and previous pages 
(arrowxxx) and to represent special characters (the others).
Those named tm_xxx are the icons used in the icons bars and by me none 
loads even the so called RGBA (copy for example).

And despite the fact that, as David said, the license concerns LZW 
algorithm and should end this year, there are a bunch of graphics 
applications which have (currently) suppressed the possibility to use 
or save as gif files. So, it appears to me (maybe silly) that those 
files should be better true png files to avoid user's non-capability to 
see them. Then as a side-effect, we'll have only to deal with ps and 
png files inside the whole manuals (it's already difficult enough to 
have something which loads correctly on all platforms, without adding 
unnecessary difficulties, sounds to me like laying one's head on the 
block.)

By the way, I've tested the new Fink today's version, works at the 
yesterday's.
