Hero w/ CTA Module taking much longer to load graphic in Outlook for certain emails - am I missing something?
I'm having a problem with something that has previously worked just fine but isn't now.
In the default template, the Hero w/ CTA Module should look like this in my email blast when it arrives in Outlook:

But when it arrives in Outlook, it looks like this:
It can take 5-10 minutes for the blue background graphic to show up in Outlook. The background graphic file size is small (29kb), and it's a jpg. I have other email blasts utilizing the Hero w/ CTA Module module with different jpg files, and they load just fine. The jpgs are the same size (30kbs).
Am I missing something to optimize it so that it loads faster?
