Post [BUG] Serious Breach Of Forum Protocol 
 
At the moment, the way IP caches off-line images leads to compromising other website / server restrictions when it comes to hot-linking.

The two images here DO HAVE "NO" hot-linking at the server and functions normally with other forum / website software.

For example if you "Click" the images below - you get what you should only be seeing when this post / thread was submitted.

Whether you like it or not - This is serious, and in the current format that the restricted images are being handled could raise some serious objections as to the integrity of IP.

Edit:

Unfortunately I've had to revert back to squashing hot-link prevention for now for other reasons, but the fact of the matter is IP should not cache the "Preview Image" - rather it should cache the off-line "linked" image when the post / thread is submitted.

Well... unfortunately there is not an easy way to achieve that.

When the images are posted the first time they are cached and then never checked again until cache is emptied.

So if you post an image which is visible and then you enable "NO HOTLINK" the image in cache will still be shown for thumbnails... if we force to check every time the source then we will have no benefit from caching.

I wouldn't call it a bug... it is the way caching works... and that is the issue for every kind of cache.

We need to chose the correct trade-off between speed and "true dynamic" output (which is tremendously slower...).
