How to eat the server path in freetextbox

In the past few days, I moved all the emails of danceshopper.com to the DB.
Edit the email template through freetextbox on the front-end page
However, the image path in the email is always lost after PostBack, for example, src = 'HTTP: // www.dances?per.com/images/01/gif'
After saving the file, it becomes src = 'images/01/gif', which makes people very faint ............
Later, I went to his website to prepare for a contest. I saw this article in the Forum. Image: Hostname stripped on PostBack

Great.
Set Removeservernamefromurls.
Don't say you are lazy. I carefully read his help and didn't mention this property. The free stuff is worse, both in China and abroad.
