The simplest way to clear the pics is to set your "my comments" page to "brief" rather than "full". That option is at the top of of the screen, in the right corner. Keep it that way until, in the fullness of your posting activity, the offending post has scrolled away.
I use Firefox for a browser, the nice thing about Firefox is all I have to do is right click my mouse and select "Delete" and I no longer ever have to be bothered again with that picture.. This is especially great for dialup FReepers like me that enter threads with numerous large Bandwidth sucking pictures. While they are trying to load, I quickly block them and presto, my page loads very quickly.
