I just got an epic pm from my friend that has to get sigged but ive read the guides on how to post screen shots but can someone put it in extreme lame mans terms?

OK so you've saved the image right? If so then make an account on imageshack (I have more experience with imageshack than with other places, so I'll talk about there.)

 

 

 

You may have to confirm a email which should arrive to you in 10 seconds of making an account.

 

 

 

Now you can either go to http://www.imageshack.com and the immediate option is browse image, here choose your image and press upload. It will take about a minute to upload. Then copy the direct link and paste it into your signature.

 

 

 

If this interface doesn't appear when you go to imageshack.com select "My images" and then there should be an option to upload single or multiple images on a toolbar to the right.

 

 

 

EDIT: There is a sticky on this two posts above this.
