Hi,
TFU supports plugins already since 2.9 but I never had the time to create a website for them. Now it’s done. You can now easily do something after the upload. For the beginning I have created 3 simple plugins: log to the tfu.log, log to the database and create a thumbnail after the upload.
You get everything you need to know here:
http://www.tinywebgallery.com/en/tfu/web_plugin.php
So you can already use the plugins with the current version. In later versions of JFU I will add support to install plugins in the JFU backend as well.
Have fun using TFU/JFU/WFU,
Michael
