Some emails display images as http address
I have a new Macbook Air. I get regular emails from eBay, etc and they contain images. Lately some emails, not all, do not display the images. Instead there is an HTTP address that if I open takes me to the images in Safari. I have all the settings to display HTM images.If I check the same email message on my iPad or iPhone it does show the images. The problem is only on the MacBook Air. Any thought on fixing this??
