ps, if anyone knows how to convert pdf to jpg let me know. My intent is to be able to post pics of patents, such as the one above.

If you download the .tif file from the patent site most image editors like Irfan View will convert from .tif to .jpg.
Or you can reduce the size of the .pdf file to around 50 per cent, left click above the upper left corner of the patent picture and draw a box around it to highlight it. Then left click and copy (or control & C on the keyboard) and paste (or control & V on the keybord) in your image editor. This will give you a .clp file which you can crop, resize, name and save as a .jpg. That's what I did to get the pic below.
