The successful flow to display a thumbnail is this: The UI request the ECL item (if you have opened an item) or a list of items (if you are browsing a folder in thumbnail view). The Tridion UI builds up a URL for the thumbnail. This URL will include the etag returned from the ECL provider as well as the requested size - ensuring any change to the thumbnail ...

ECL URI's have a maximum length equal to the maximum length of a Component title. This limitation originates from the stub components having the ECL URI as the title. The intended behavior when caching thumbnails is to stay within the 260 character limit on a file path by cutting the URI short in the name of the file used to store the cached image. In ...

One important point to understand is that ECL mountpoints make a connection to an external system, this will always introduce latency and thus can have a huge effect on the performance of the UI. For each mountpoint there will be multiple connections made to the external system, when browsing through the tree of ECL items and when opening ECL Components. ...

By design ECL will refresh thumbnails when either: The etag change The version of the ECL provider change I can't remember if it will also regenerate when the version of ECL (so Tridion) changes. Typically I would expect this behavior if the etag is not calculated identically each time. To verify it, identify a cached thumbnail to check. Rename it to old....

The problem is in the provider, so your solution is also in there. DO NOT try to change the stub after it has been created, a stub Component for ECL is supposed to be a hidden item that is there for internal purposes only, and when you try to manipulate it, you will create issues in ECL (there is an event handler which will already prevent you from making ...

So looks like you need to specify the <S3RegionEndpoint> and the <FullBucketUrl> within the ExternalContentLibrary.xml S3 configuration I got from here. <S3RegionEndpoint xmlns="http://www.sdltridion.com/S3EclProvider/Configuration">us-east-2</S3RegionEndpoint> <FullBucketUrl xmlns="http://www.sdltridion.com/S3EclProvider/...

At this point (8.5) only the CM supports this indeed. For that same use case you're asking about I'm currently designing/building a solution with ECL instead. The file as stored by the CM is unusable outside of the context of the CM itself, and this was built in 8.5 merely as a way to alleviate DB storage requirements in CM, not as a way to bypass or ...
