Here is how I do it.
First I open two browser windows in Firefox. I open both to Woodworking talk. In one I begin my post. In the other I open the userCP and go to the album with the photo I want. Then I go to the actual photo. At the bottom of the photo there are two selections.
One is HTTP code and the other is IMG code.
Left click on the img code and it will highlight the entire string. Sometimes it takes more than one try.
Now switch to your post and paste the img code.
Now continue typing until you want to place another photo. Then repeat the process.
Don't simply right click on the picture from the album, open the actual picture, then left click on the code. Then switch back to your text and paste the img code.
