Hi, When PNG images are resized (and saved) my my mediawiki (1.10) on IIS, transparency is changed to black color! I've used no external app for resizing PNG. PHP does this automatically.
Thanks.
You need to install ImageMagick or GD Library and configure its use within MediaWiki. Instructions on how to do this can be found here: http://www.mediawiki.org/wiki/ImageMagick#image_thumbnailing
HTH.
