I can't seem to attach photos anymore after a W10 update. I see that the formats are JFIF now rather than JPEG, and windows seems to change them automatically. Is there any way we can attach JFIF pics here?
This is what I am getting when I try...


ERROR
Invalid file extension: bulb 1.jfif

Mantou will either need to add an extension that allow the new file type, or you can convert the JFIF to more portable type such as JPG or PNG. This should move to the Off Topics forum, however.

I opened pics with Paint and saved as JPEG, so now i can attach.
