So you are in favour of a "internal_ext" extension.

The only extensions which can come into conclusion are those supported by both: gdlib and IM
cause images get writte/read by the one and read/written by the other (and vice versa :)

That leaves us with:
png,wbmp,jpg,gif In the order i would them prefer for colorful images or:
png,wbmp,gif,jpg In order I would prefer them for black/white images or low color high contrast images

An autodetection could get done in the install tool where the matching combinations for gdlib and IM are
evaluated and intersected and the best one in one of the above orders (colorful ?) will get choosen


You will have to discuss that with Michael who is in favour of letting the user only set gdlib_png to 1
and everything (internal and output) is in png ...

in my opinion the internal_ext option is a nice feature for people who like to show "look we have old (school)
gif on our page which are supported by every browser" :) I for myself prefer generating pngs.

Decide quickly because it should get into beta3.
