Manual talk:Thumb.php

After some changes in MW configuration thumb script refused to work (it worked in the very beginning, I'm sure of that) - I mean, browser waits for its answer for eternity. After I wrote $wgThumbnailScriptPath = "{$wgScriptPath}/thumb.php"; (what has always been true), it generates frames but there are no images inside. What could it mean? MediaWiki 1.13.2, PHP 5.2.9-2 (apache2handler), MySQL 5.0.67-community-nt

I have this problem with PHP Safe mode, (which I can't disable). This is because it's still trying to write the thumbnail to the images\thumb directory. It needs to be creating the thumbnail and streaming it to the client instead. When you say it was working before, I'm guessing it was just using client scaling, i.e. it was sending the full size image and relying on the client's browser to squish it down.
