Maximum file size of images to cache (in KB)

[PrimalPrime]

Maximum image size that the SSL image proxy will cache: bigger images will be not be cached. Cached images are stored in your SMF cache folder, so make sure you have enough free space.

Could someone explain this to me? If I plan to host really big images, what should I set this to?

If you are planning to host them, as in load them from your own domain (attachments included) or another https source, the setting makes no difference.
