When i try open an image it says:
No apps installed that can open “user_files”. You can find more applications in Software
@zyph, what is the file extension of the “image” file you are trying to open? The error indicates the file extension is “user_files” which is obviously not image file extension? It is also possible your “image” file does not have file extension at all. Make sure file has proper file extension, if not rename the file to have one.
If you can’t solve the problem, I suggest to report bug at official Anki’s bug tracker, but please provide more info, like what is your image like, what file extension it has etc.
