Hi @SamSimpson
If you want to use the default search functions in ArcGIS Online or Portal, no it is not possible to search for images or other resources attached to an item (Site page, storymap etc). So you are correct there.
Using the ArcGIS API for Python, you can retrieve the existing resources on an item and list the file names and display them. This requires that you know in advance which Site page or storymap you want to find the image.
That is what happens in my Python Notebook:
page = gis.content.get(pageid)
resources = page.resources.list()
for resource in resources:
#do stuff
You could extend my script to build this search functionality, should look like this on a high level:
- Get all items in your ArcGIS Org
- Loop through all items, retrieve all resources
- Loop through the resources, try to match the resource name and yield it when a match is found
Wouldn't advice to do this, because there is no index, so doing something like above would take a lot of time if you have a lot of items you want to search for the image.
I'm working on a Angular, JSAPI4, Calcite fun project which gives me a nice UI UX for some admin tasks, might add a item resource browser to it as well. That browser should show all resources, offer update and delete functions and of course render the image when it's an image. Shouldn't be too much work 🙂
Will let it know here when I build that feature and when and where it's available.
