External image caching

[simon816]

I should point out that the forums are a temporary place to put plugins.
When Ore is ready it could be possible that we don’t cache images.

There has been some previous discussion on image caching, see:

Dynamic images

I’m trying to put a “dynamic” image that changes over time but the forums keep changing it to a custom one from the server. This is the notification I get http://gyazo.com/0ea8f9a0cd5e4d1679e96f08461de4b9 and the image being changed. Can I solve this in some way? Thanks.
