Gerd, I did not "display" _any_ images; I merely process-marked them and
pressed "o" to download them.

1) I suspect that the "display" code is activated in download contexts
   where "image-cache-eviction-delay" is not used.

2) Is it possible that display-oriented activity is happening
   unnecessarily in "o" download contexts?

In case it matters, my custom-set-variables contains:
 '(gnus-default-article-saver (quote gnus-summary-save-in-file))

Apparently clear-image-cache is not being fired when expected.

I set it from 1800 to 18 and it did not help.
