I was just wondering, is there any way to make FG save the screenshots as jpegs instead of pngs? I was just wondering because the wiki doesn't seem to take pngs and neither does my television.

The mongoose based Phi front-end does support jpeg - apart from that, I've been using/uploading tons of pngs to the wiki

i haven't had any problems with png files on the wiki either... i have, however, had to reduce their size... the wiki does have some size and resolution limits in place... here's an example of one that i posted on the wiki...

i had to reduce it from the original 1600x1200 to 1024x768 for it to be accepted... reducing the resolution also reduced the actual file size...

edit: hummm... i wonder if the second ':' (colon) in the URL is causing problems with phpbb's img url processing?

Reason: Nothing wrong with bbcode, you just did not link to an (pure) image file, but a wiki page with an image on it ;-)

If you have GIMP you can run it in batch mode and use a script-fu on the images to convert them, I've never done it but I've seen it talked about quite a bit. This gimp page might help. There is also a script example to convert xcf to jpg which might give insight on how to convert from png to jpg.

No, not without changing the code. To my surprise FlightGear can (currently) only take .png screenshots. In essence it is the only format implemented. Before 2013 FlightGear also could take .ppm* screenshots (prior to commit 362d47).

The screenshot code resides in simgear/simgear/screen/screen-dump.hxx and screen-dump.cxx

* Portable PixMap. There is both a binary and an ASCI encoded human readable(!) format, though I am quite sure FlightGear used the binary format. ;) For history and specification, see the Wikipedia article Netpbm format (perm)
