[Mediawiki-l] Image resize not working

[zham rock]

Hi,

Here is my system:

Solaris 9
mediawiki-1.10.1
imagemagick-6.3.0
mysql-5.0.45
Tim Starling Imagemap extension

source code:
<imagemap>
Image:Computer.png|80px|My Docs
default [[My Docs]]
desc none
</imagemap>

LocalSettings.php
$wgEnableUploads       = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/sfw/bin/convert";


Here is the problem:

i have my icon which actual size is 132x132, if i resize it to 80px it
doesnt show, but if use 132px it shows.

Please help.
