Bart,

Well, it isn't implausible to imagine fixing up the built-in png, gif and
jpeg support to handle 24bit mode.  They definately will not support
reprojection without a major overhaul.  But Steve and I have generally not
felt that it is worth spending much effort on the old non-GDAL raster input
sources.  So if you, or someone feels a minimal build for such a configuration
is valuable, there would be some development work to be done.

I quite understand about a minimal build. GDAL is a big whack of stuff.  If
size is a major issue there are ways of building "pared down" GDAL's.  But
that doesn't help much if simplicity is your main goal.

Best regards,
