I will try to help you out here with the photos (I can't see them) -
I forgot that in Flickr, you have to right click on the pic to get the correct url.
Right click on the photo and select "properties" in Flickr to get the url, which includes the .jpg extension - this is it for one of the pics:
http://farm3.static.flickr.com/2749/...19a8dea7_o.jpg
Then use the img tags before and after the url, or use the image button in the SSP post window, and you get this:
If your not sure, just quote this post to see how the code looks.
Hope that is helpful.
What you did wrong was you took this url which is for the whole page and not just the picture:
http://www.flickr.com/photos/4516084...n/photostream/
I am not that familar with flickr myself, so there may be easier ways to do it.
