Just to make things more complicated (well actually, to try and reduce the page loading speed still more ;-)) I’ve moved all the images on our website to a subdomain. I changed the URL for the path to media in the settings on the dashboard, and updated the database with the new url.
The images are mostly loading but the thumbnails aren’t being generated in the right size and they’ve lost their movement/wiggle when you hover over them, and the background (featured) image on the blog pages no longer load at all.
Any ideas what could be causing this? I tried deleted and reinstalling the Dynamic Thumbnails plugin but it didn’t make any different. I’ll pm you the link.
