BleepingComputer.com: Easily converting hex code to image

Windows Vista x64
Firefox 3.6.10

Does anyone know of a quick/easy way to convert the hex data in about:cache-entry?client=HTTP&sb=1&key=http://link to imagehost/folder/filename.jpg ?
While it's a small image (thumbnail), that's still a lot of numbers and letters to type. I tried pasting it into Notepad++ with the HEX-Editor plugin and saving as .jpg, but it wouldn't open as an image.
Hopefully there is some magic trick so I don't have to type it all out manually.

Thanks.

After converting in NotePad++, press the [Alt]+[Print Screen] keys, open "Paint" and paste. Crop as needed, then "Save As". Or after converting in NotePad++ you could use something like PicPick to "capture a region" and "Save As".

Thanks for the reply.
I have given up for now, as it wasn't an important image in the first place (and I forgot to save the data before Firefox cleared it ). I'll know what to try if I come across this issue again though.
