Hello,
First, thanks for your work. It's an extraordinary work you do, so keep doing that

But, I've a little problem :
Users upload images, but only connected users can see these images. Guests can't see these images. It's quite strange. And when I click on "open the image on a new tab" where there is normally the image, I get an error on a blank page : "not-allowed".
It's really strange... I was thinking of a permission error. Can you help me pls ? I already tried chmod 775, 755 and 777 on upload folder and it didn't work.
