Converting image file formats, e.g. *.png to *.jpg

[TheDead]

Yes my bad. I just checked and for "save a copy" you have to open the *png file in ristretto, click on "file" menu and there it is; "save a copy" then simply when saving rename it adding the *jpg extension and that's it. Guess I forgot this "little" detail. Sorry about that 

NP, I'll have a look at Ristretto in the future. I havent really looked for a quick viewer, I've been using xnview for year on 'doze, one of the first program I usually install to replace the too-basic one in this OS
