It is in the different language but you will see on the right side "Prijava" which means login...
You appear not to have understood
the language fallback concept of coppermine: for us, the navigation displays in the language we have set up in our browsers. For me, it displays in German. For Nibbler, it (usually) displays in English (or at least: it should). You can force the use of a particular language by modifying the URL accordingly. To see your page in French, I went to
http://livnograd.com/cpg149/index.php?lang=frenchHowever, I wanted to see your page in English, so I went to
http://livnograd.com/cpg149/index.php?lang=english, but that didn't do the trick: you appear to have replaced the
English language file with the one for your language. This is not a bright idea - if you don't want your page to be visible in English, then remove the English language file. It would be better though if you put the original file back. Did you "optimize" some other files that we should be aware of?
This being said I tried uploading with the German language set (as suggested above, the English language file would have been my favorite choice to come up with an English error message as well). This is the error message I got:
Kritischer Fehler
Das Bild 'albums/userpics/normal_actualconservatorioantiguopala.jpg' kann nicht in das Album eingefügt werden
Kann Thumbnail nicht erzeugen.
which translates into English as follows:
Critical Error
The file 'albums/userpics/normal_actualconservatorioantiguopala.jpg' can't be inserted in the album
Unable to create thumbnail or reduced size image.
This usually indicates two things:
- coppermine can't write the thumbnail because of permission reasons, so you should review the permissions on the albums folder and everything with it (refer to the corresponding section of the docs)
- there are issues with the image library you specified (Image Magick or GD), so you should review your config sections for "Method for resizing images".
