Please do the following:
-Import a Cache, which contains an Image in the Description (e,g, GC1F8ET) _without_ Image Import at first.
-Go to the Cache Description
You´ll see the text, the attribut Icons and that rotating "Thingy", formerly known as sandclock ;), but the image ist not loaded.
I´m not sure, but i think, formerly this Image was loaded online.
This happens from V500, perhaps even earlier versions.
Please reactivate that online Image Import again.
For me, there is no need to Import ALL Images for a complete PQ, i´d like to do that on demand automatically (i´m not talking about spoiler import)
