Sure, here's your plugin. Copy + Paste that block of code into a file 'serendipity_plugin_imagecategory.php' and save it in the directory 'plugins/serendipity_plugin_imagecategory' of your Serendipity installation.
Then you can go to "configure plugins" and select the new Plugin 'Image Category' and add that to your plugins.
It will then display a second icon for every category for which a file exists. Let's say your Category is called "photoshop", then you must have a file called "templates/default/img/photoshop.gif" which will be displayed. Pay attention to upper/lowercase of the filename, and all characters whice are not A-Z or 0-9 need to be replaced with "_".
Code: Select all
