I think you are still able to post pictures from Imagestation, when you copy the location of the picture, for some reason its adding .orig.jpg to the end of the location.

Here is picture location the bbs is trying to show for your first picture.

"http://www.imagestation.com/picture
/sraid20/pa4e728bc55f676a501af50ae036b0261/fdbae581.jpg.orig.jpg"

It should only be

"http://www.imagestation.com/picture
/sraid20/pa4e728bc55f676a501af50ae036b0261/fdbae581.jpg"

You may just need to be sure the extra .orig.jpg is not on the end of the location.
