Pictures not showing

[Eszaraxe]

After I uploaded the pictures, it was working, but now, a few days later, the pictures are not showing anymore. Accoring to the album information, there are pictures but they are not visible? What is wrong and what should I do?

You probably deleted them via FTP. Check that they are still there.

I have not used FTP since I uploaded the pics, but I checked now, and the pics still are there.
