Donation Thermometer is a module with an editable image of a thermometer similar to what you would have seen at Church fund raising drives. The original module was based on an open source script creation of Arkie.Net but has now been completely remodelled from the ground up eliminating the need for GD Library. The width, height, funding goal, current amount raised, date last updated and currency can all be adjusted in the module's parameters. As well as a few other options including caching, module suffix, html pre-text and post-text. This is my first attempt at a joomla extension so go easy on me :) If you know how to improve this module (like implementing IPN integration with paypal, so that the thermometer auto updates with each donation) please let me know.
If anyone would like to contribute to the development of this module, please contact me and I'll add you as a project developer on joomlacode.
