This is actually a interesting thread.
The poster who said they were still on dial-up internet access really got my attention.
Obviously for such a user they cannot tolerate embedded images so they have to have just a link.
Then lost links:
I have received emails from people looking at a post I made years ago that the image links were broke.
I usually post from my website but got dumped by my host so those links from the past are lost.
Sometimes I have been able to find the images but often I cannot they are lost.
