Remove thumbnail field for images from the catalog

[obulat]

Current Situation

We get the thumbnail URL field from the providers but do not use it because we use the thumbnail proxy instead.

Suggested Improvement

We should stop retrieving thumbnails from providers.
There are several things that need to be addressed here:

• Remove the thumbnail from provider scripts.
• We probably do not need to remove thumbnail from the common columns (TSV and DB) as audio (and maybe other media types) use them. I think it would be easier to set the image thumbnails to NULL.
• Clean up the database?

Benefit

Slightly-improved performance and less data to store, data consistency.

Additional context

Implementation

• 🙋 I would be interested in implementing this feature.

Interesting! Would removing this have any implications for video or 3d models (not sure if models have thumbnails but I hope so!)

Well, I think we should leave the thumbnail field in the catalog as the field that is used for all types of media, but set it to null for images. We will need to investigate whether we want to use the thumbnails that are provided by the providers as we do with audio, or generate them just as we do with images.

Okay! That makes sense 👍
