konqueror: "Block images from this site"

Well, I screwed up and clicked this option in error after right-clicking on an image (planning instead to click "View Image.) And, it just happened to be ONE OF MY OWN WEB SITES! sigh... Well, no problem, right? I just go into one of the menu dropdowns, select the appropriate function. and delete the web site from the list (which otherwise should be totally empty anyway.) No joy. No such dropdown --> function that gets me there. konqueror 3.5.10 trinity 3.5.13.3 In doing a web search, I believe what I want is Tools --> Manage Images ... or the somesuch. However I have _NO_ Tools --> Manage Images. My Tools dropdown contains Find file ... <<-greyed out HTML Settings Minitools Translate web page Archive web page Change browser identification I can find no way to "Manage Images" in konqueror Ok. Then I need to hack some .cfg or .rc file I suppose. Which file ... where? (Doing a recursive grep did not reveal any such file.) (Or else, my grep-fu is inadequate.) (I guess I could change my domain name ... :-) Many thanks in advance! Jonesy
