Broken image links in Design Studio

[PikeStLabs]

Looking on the forum it appears this has been reported before but I don't see a solution. Basically when I upload images to Design Studio they all show up as broken links. That means I also can't preview my designs to ensure the layout is correct because I get the broken link icon. If I paste the URL directly into the browser it is fine and if I email myself a sample it works. What am I missing here? Am am uploading the images incorrectly or referencing them incorrectly or something? 

More oddly, if I preview using 'Segmentation' I will see the image but if I preview using 'Person' I don't.

Open your browser's F12 Console and you'll see the exact reason for this.

Thank you. This appears to be caused by a redirect from HTTPS - HTTP (mixed content) issue. How do I setup a SSL or change the location of where the images are stored to a different location?

Mixed Content: The page at 'https://app-sj21.marketo.com/#FI0A1ZN925' was loaded over HTTPS, but requested an insecure element 'http://[removed for security]/images/seattle.jpg'. This request was automatically upgraded to HTTPS, For more information see https://blog.chromium.org/2019/10/no-more-mixed-messages-about-https.html

Add app-sj21.marketo.com to the insecure content Allow list.

Note all browsers enforce this differently. In Chrome it's Site Settings » Additional Content Settings » Insecure Content » Allow.
