I've had a site developed, but the original developer is unavailable and the site is currently unusably slow.
If I disable imagecache external module then the page loads very quickly (but with no images). If I enable it, then the page can take up to one minute to load. I know it has to get the images, but there are only 12 images and they are ~3KB in size so, it shouldn't take anything like as long as it does.
I'm pretty sure imagecache external is called in the bespoke module that's been developed for me, but I'm lost beyond that.
