Hello everyone,

I am currently working on creating a StoryMap and need to incorporate a map with custom symbols but they don't want to appear. In ArcGIS, they appear just fine at all scales but when I try to pull up the map in StoryMap they do not appear. I tried switching to some of the other provided symbols and those appear just fine. I'm wondering if it could be the file sizes of the custom symbols? I'm not sure how to get around this and have tried resizing the images as well with no luck. Due to the information, I am not able to publish the map just yet but I hope that I explained the issue well enough.

Any and all advice is appreciated!

Thank you!

Hi Natalie Burgos‌ -- Where are the images hosted? If they are hosted on your own server they are likely being blocked by CORS (web security) cross-domain policies.

Can you host the images on ArcGIS Online instead? Just upload them as image items, share them with Everyone (key step!), and use the URL shown at the bottom of the right sidebar to add them to your map. Images hosted on ArcGIS Online won't be blocked by CORS issues.

Great! Thanks for letting me know.

We also recently made some changes to how some content is proxied within StoryMaps, and for future projects you may also be able to use image symbols hosted on other servers.
