How to manually set a cover in Musicbrainz Picard?

Is it possible to manually set a cover for a given MP3 file instead of letting the program automatically fetching it from the web?

I have noticed that I can alter every other field to my liking before saving the tags to file, but I can't manage to set a custom cover.

If it makes any difference, I'm using the Linux version on openSUSE 13.2.

Solution 1:

I just found a workaround: you can go to "Options...", "Cover Art", then uncheck all coverart providers from the list, and click OK. Now you can still autotag the audio files, but Picard will not download any cover picture; from now on, you can drag and drop your own cover picture to the little black square on the bottom right corner (the one with a CD icon on it), then hit CTRL+S to save. It's not very practical, but it works.

Solution 2:

You can add custom artwork by dragging and dropping an image file (preferable JPEG or PNG, but I think TIFF and GIF would work, too) to the cover art box.

This is a somewhat hidden option. Proper custom cover art support for Picard has been requested for a while, but so far nobody really took up the task.
