Photos not loading : spinning wheel forever

It was pretty hard to find the problem… but it seems that the character ‘ is not allowed in the description title of a picture inside a gallery! It leads to a never ending spinning wheel, whithout loading the pictures.

We use a lot of ‘ in french, and I wish we could use it in titles…
Well, at least, I wish there was a warning notice close to the form, telling not to use such characters. Maybe in a future update?

Just wrote this message to help any people getting the same bug.
