"Save images" add-on no longer working?

A few days ago when I tried to save an image with this add-on I got the following message:

“There was a problem saving the image(s).
You may not have permissions to write to the save folder or there is an error with the file name. Please check the permissions of the folder and check the file name options.”

This has occurred to multiple people now so I was hoping someone could help us with this issue. My failed attempts to fix it:

Checking the properties of the destination folder
Changing to another destination folder

Have you tried contacting the developer of the add-on? There’s usually contact information in the page you installed it from.
