+1 on existing log viewers being particularly well suited for text over non-textual assets. My experience here is limited but I believe Grafana has a dynamic image plugin if you store a link to an asset in blob storage or Base64 encode it.

I've also heard of people storing those links in a database like Snowflake then creating displays on top using Tableau or Looker, to avoid having to build a web app from scratch.
