I think this is a bug in WebKit. I suspect that it's the WebCore
cache that's causing the trouble. It would be great if you could file
a bug report, especially if you could provide a test application to
use to reproduce it.
For now I allow all image loading, but it's a real performance
issue in my application. I load a lot of Web Pages using Web Kit in
"hidden" WebViews and just analyze and modify their DOM (for that I
don't need any image loading), and then just a few (or one) page of
them is displayed in a visible WebView to the user. If I prevent
all image loading in the hidden WebViews, the performance is much
better, but then also the visible WebView does not display the images.
You may have better luck if you use -[WebPreferences
setLoadsImagesAutomatically:NO] on your hidden web views. You can set
per-WebView preferences, and I think that works fine.
