To post the images from your profile, click on the thumbnail to open the page that the image is on and then copy the image location. On a Mac you hold down the control key while clicking on the image which will give you a pop up menu and you select the "copy image location" option. Then click on the "IMG" button in the menu above above the reply window and paste into the "IMG" window without clicking on it. The image location will be pasted into the "IMG" window. Then click OK and the image location will appear in your post, formatted to display when you post. I can't remember if it's a right click or a left click on a PC, but either way, when you get the pop up menu, select "copy image location" and paste it into the "IMG" button.
