Hi Paul....I don't have the res fix so can't help you there but I can get you through the posting of screenshots procedure.
Go to
http://imageshack.us/
Click on Browse (notice I have my image size set for a 17-inch monitor, it doesn't have to correspond with your actual monitor size, mine is a 22" flatscreen but I like the look of that size on this forum, the larger the size selected, the larger the image will be on the forum).
The file box will open, go to wherever your image is stored, in this example the desktop.
Click on the image and select Open.
Click on the UPLOAD NOW button.
Your image will upload and show a small thumbnail, I'm using one of my Police photos.
Underneath you will see the Forum Code....left mouse click to highlight it then right mouse click to choose Copy.
Go to your forum message and right mouse click paste and the code for the image will appear in your message.
You can check by using the preview message function on the forum.
That should see you good to go
