Adblock Plus

i accidentally clicked "block cdimg2 from cru..." to a picture. and now some pics of the site won't show up to my com. support said to click adblock plus and a list of items will pop up. but i did not see any list written when i open it. i think it is because i did not install the adblock plus before i blocked a pic. does it affect it? i really wnt to undo what i have done. what am i going to do? could anyone tell me how?

You did not block it with Adblock Plus. You blocked it with the built-in block function of Firefox. Go to Tools -> Options -> Content and then click the 'Exeptions' button to the right of 'Load Images'. You can remove the affected URL there.

Iam looking for this, Tks.
