Netlife's Flash Tag Cloud plugin for WordPress - FatCloud! Wordle your WordPress. Beautiful tag clouds that are accessible & SEO friendly.
FatCloud has been successfully tested with WordPress 2.7.1 on PHP5.2+. We have not tested it on 5.1.x. There is no support for PHP4 (sorry!). If you have problems on these (or other) configurations, feel free to submit a comment on Netlife.
Our initial release did not allow for a different plugin folder name. If you downloaded version 0.1, parse errors are expected after activation i.e. 'parse error, unexpected =,'. To resolve this temporary issue, FTP into your website and rename the plugin directory from 'wp-content/plugins/netlifes-tag-cloud-fatcloud' to 'wp-content/plugins/wp_fat_cloud'. We have since pushed up revision 0.2 to resolve this issue.
FatCloud is doing some pretty hard-core rendering back there. Once it renders, it caches the render data on the server, but it needs to re-render whenever its data changes. A 45 second render time is pretty normal. It will happen only once after a new tag is added to wordpress.
