Paperclip gives an strange error message

I installed my railsapp on my server and now i get a strange error when
i tried to upload a photo.
On my macbook it works well but on the server i got next error when i
create a new post

Photo /tmp/stream.22042.1 is not recognized by the 'identify' command.
Photo /tmp/stream.22042.1 is not recognized by the 'identify' command.

The message came as an error message on the website

It means the ImageMagick installation on your server doesn’t recognize the file you’re passing to it (for processing). It can be a number of things:

  • ImageMagick not compiled correctly

  • ImageMagick compiled correctly, but not with the library that processes the filetype you are giving to it

  • Some other stuff that doesn’t come to mind right now :slight_smile:
