In galleries, you don't need the "File:" part, but as Expert said you need the correct file extension in the code.

I had a similar issue with Visual Editor a while back, when edits were published the infobox would show up as one line of code. So I was advised to switch to the Classic Source Editor, which I had prior experience for from other wikis.
