I have $conf['fetchsize']=0 in my config. Does it mean that the caching
is disabled? Or the the contrary, images of any size will be fetched?

And one more question: if remote image is not available anymore, but was
previously cached, will it be displayed or will it also expire from
cache? I dream about the feature to have the images in the cache forever
:) My disk space does not matter, but disappearance of remote images is
very annoying.

Thank you!
