You must have an existing place on the web to post your pictures.
Once you have them posted on an existing location to add them to your GHQ post you simply click the Img button second from the right, which will give you an

, ...and your done.
Do a Preview run before posting to make sure you have all the information correct.
If you screw up the address you can return to your picture via the web, click on it and go to properties, ...to get the correct address information which you will not be able to copy, but will need to write down to get it correct.
I wish GHQ had the ability to store the pictures used on their site because the pictures I post take up space on the web site I have shoulder the expense for, not that there are too many of those, but in some cases a picture I post to help someone else understand a concept that benefits a GHQ customer doesn't really apply to my company's web site. Just a small thing, but one that eventually needs to be addressed.
