Like many forums we had been affected by the shenanigans of Photobucket.
At present Photobucket images have been blocked by Forumotion to save filling the forums with Photobuckets horrible messages demanding money from their users.
The basic forum background and banner and most other site images are now hosted by other image hosting suppliers.
When posting images, please do not use Photobucket unless your sure you are authorised by them for third party linking or use one of the many other image hosts available.
