object_location - broken Images

[saracolh]

Hi everyone 👋

I'm building a CollectionBuilder-GH project about the history of rock in Colombia:
👉 https://saracolh.github.io/rock_colombiano/

The collection builds correctly — all metadata works, and the images are located in the correct /objects/ folder.
Each image file name matches its objectid in the metadata CSV, and all image URLs work perfectly when accessed directly. For example:
https://saracolh.github.io/rock_colombiano/objects/1985-03-16_batallabandas.jpg

However, in the site interface (Browse and Item pages), all images appear broken — the thumbnail and featured images don’t display, even though the files are there and load fine if opened individually.

I’ve already checked:

• _config.yml (URL and baseurl are set correctly)
• The object_location field points to /objects/<objectid>.jpg
• All filenames and paths match
• The images are visible locally and on GitHub

I'm using GitHub Desktop to push updates, and I can see all images correctly in the repo and on disk.

Could this be related to how filename or object_location are referenced in the templates (like _includes/image/featured-image.html)?
Or maybe something changed in the GH theme behavior for images?

Any ideas or suggestions are very welcome — thank you so much in advance!

Best,
Sara Colmenares Hernández

Hi @saracolh!

For CollectionBuilder-GH, you'll need a filename field in your metadata that lists the file connected to the item. You don't have one, so the code doesn't know where to find the images.

Here's the CB-GH metadata>filename documentation

Since your filenames are just your objectid + '.jpg' you should be able to add these via a forumula in Google Sheets.

Note that if you don't specify a precise location, CollectionBuilder will look for your image in the /objects/ folder. Since your images are all in that folder, you just need to add the filenames themselves to the filename field to make them appear.

Good luck! Let us know if you have any other issues.
