The problem with embedding, vs. attaching images is that often times you will eventually take down the picture from the external source, and then the picture will no longer display properly in the thread. So if someone comes back in 3 years, does a search, and finds a thread that should have answered all their questions, they might find that none of the pictures display and therefore the thread is worthless to them.

If you attach the pics, then they will stay up as long as this forum stays alive...
