Images load properly the FIRST time but not afterwards

Images load properly the FIRST time but not afterwards

This is quite frustrating because it's SO close to working correctly!

It starts out fine. If I start a campaign, put in images, resize them correctly, and send it out - it looks great. Below is how it looks in the editor AND how it looks in the received email.


BUT if I save the campaign and come back to it later, THIS is what I see.


Now, if I send this campaign AS IS (no changes to try and fix the image), this is what the received email looks like:


Essentially, every time I reopen a campaign or try to use saved template, I have to re-attach and re-size every image and logo in the email.

And, to head off these suggestions:
  1. clearing the cache doesn't fix it 
  2. changing browsers doesn't fix it
  3. Interestingly, when switching to a different computer (same Windows Pro 10 operating system), the problems didn't occur. But DID show up again on the original, primary computer.
What can be the issue? I need this to work on my primary computer!
