It looks like you copied the imagestation address instead of the individual picture at imagestation. When you want to link pictures from Imagestation, do the following:
First, choose the pic at imagestation you want to use. Make sure you have the full version up on the screen, not the thumbnail.
Second, right click on the *actual* picture and choose the Properties option from the menu that appears. Then, copy the address (URL) shown under the Properties tab.
Third, come back to this site and start a new message. Click on the IMG button (located above the box where your typing the new message). Here you will paste the address you copied from imagestation.
Fourth, once you copied the address make sure you have not dupliced the http://
at the beginning of the URL, and delete the orig.jpg that may be at the end of the URL you just pasted. I use imagestation all the time, if your still having problems PM me!
