This was what you were trying Naquin? You almost got it.
1) Go to gallery and view the pic
2) Right click on image, select "copy image address"
3) Make a new post, click on the yellow mountain icon that will say "insert image"
4) Paste the image address
Just see that the address has pictureid= number at the end, and you get both IMG in the front and /IMG in the end.
