Bitmap image thumbnailing on MediaWiki

[linuxx14]

Hi,

I have set up MediaWiki with x10hosting but the problem is I don't know what command invokes ImageMagick's convert tool on x10. I have tried:

$wgImageMagickConvertCommand = '/usr/bin/convert';

$wgImageMagickConvertCommand = 'convert';

and:

$wgImageMagickConvertCommand = '/usr/sbin/convert';

But not one has worked.
