I just do a "print screen" command to a file. Then insert the file name as a pic in the post. It only works on one of the computers (not this one). Somthing to do with set-up for the print screen command.
Try left clicking and draggig your mouse to highlight everything you want to transfer, when it is all highlighted right click and then click on "copy". After that is done got to your post and right click and click on "paste" and it should put all the highlighted info in your post automatically. Just something else to try.
