Those messages have to do with your PHP configuration and shouldn't be
affected by which browser you use. It's possible that there's a caching
issue that causes Netscape to see different versions of the page, or
the error messages might be hidden or displayed differently (check
'view source').

Well, that's going to make it pretty hard to shell out to ImageMagick.

If you're unwilling or unable to change that, try using the GD library
support instead (switch the settings in LocalSettings.php). This of
course will only work if GD support is available in your PHP
configuration.

It's also kind of odd that there are different path names here. Is this
a deliberate configuration you've set up, or something weird?

This is trying to remove 0-length faulty generated thumbnails. Since
the file doesn't even exist, that naturally doesn't work right.

Hi Brion,
thank you for answering.

I can observe the difference between Netscape 7.1 and Firefox 0.9 even
in the source code. So I think you are right, it might be a caching
issue of Netscape 7.1, because there is nothing wrong in the other browsers.

I allready disabled ImageMagick this afternoon, but may be the error
messages are still present (in Netscape) due to the caching issue you
mentioned.

I am sorry, this is my fault: I wanted to erase the directory name and
forgot this one ;-)

The thumbs are working well (with GD library support), so I hope the
error messages will dissapear once the cache is reloaded.

Thank you!
