I use the GIMP photo editor which automatically saves the converted files in .xcf format, but they cannot be reopened with any other app. How can I convert or save my images as JPEG or PNG?

If you use (from command line or within a script... if you need the script just ask ;) ) the command file thisimage.png, it will tell you what image format you actually have.... Then you can rename accordingly...
This is a sample of what I get with a file with incorrect file extension .png which is really a jpg file:
user@computer:$ file logo.png
logo.png: JPEG image data, JFIF standard 1.01
Edit: Oh, ok, I was lazy before... Here's an script that will rename actual gif files that are named with .png extension to their correct extension .gif:
#!/bin/bash
for NAME in $(ls *.png); do
if [ "$(file $NAME|grep GIF)" ]; then
echo "Renaming ${NAME} to ${NAME%.*}.gif"
mv ${NAME} ${NAME%.*}.gif
fi
done
There is a plugin for the GIMP, written by Nathan Osman.
You can add this plugin from his webptools PPA:
sudo apt-add-repository ppa:george-edison55/webp
Then install the required package: gimp-webp
sudo apt-get install gimp-webp
As for thumbnails in nautilus, this seems to be a bug with MIME, as apparently (so I was told) Nautilus already "supports" the webp format, but the thumbnails do not show up as they should.

You have to export the image, not save it.
To convert:
FileExportEnter a filename
It'll be saved as PNG by default. You can use any other format by simply adding the extension to your filename (like
image.jpg,image.bmp) or selecting another file format in the bottom right of the export window.Click on
ExportThe downside of exporting is that you'll only save what you see. So all your layers will be merged, and all editable components you may have added (like text) are not editable anymore.
So, if you would like to easily edit your images in the future, also save it as a XCF file as this will preserve all layers, components and other things as they are when you close GIMP.
