A few weeks ago, my images no longer display in email templates that we've created. Instead, I just get the small placeholder content. I don't believe I changed any settings, so I'm not sure why they disappeared.
The main reason of an image not working in Eloqua is that the URL of the image is not correct. To check this you need to go to the Eloqua->Assets->Components-> Images and find the image that you uploaded and make sure that the "Full Image URL" it's the same URL that you are using on the email.

I haven't changed anything, but all of a sudden Eloqua does not show the images within the email editor (even in old existing emails). When I test or send the emails, the images are there, so I know the urls are still the valid ones. This is the case with all images.
Example with the hero image:
I can still work like this, but as you can imagine this is far from ideal.

Sorry, I've solved it. It seems the issue is to do with the implementation of the secure server at the images subdomain. Before all images used to be:

I hope it helps others too. Thank you all anyway.
