I downloaded the ElJay Icon Maker Firefox extension. It's neat. I can right-click on any image, and either create a new icon instaly (which will automatically upload on the next page, assuming you are logged in to LJ) or you can create it "with options" and crop, rotate, add text, etc.
I downloaded it awhile ago and forgot about it until earlier today, when I actually read the options when I right clicked on something.
In other news, there is a mosquito bite on my knuckle. It's very painful
