feat: provide a field for compressed/ small images

[oSumAtrIX]

Is your feature request related to a problem? Please describe.

Currently, the API only provides links to full-sized images. This slows down the loading speed on the frontend.

Describe the solution you'd like

Provide an API to get links for web-optimized images. An additional field "optimized" for example. Frontends can use that field to load the image and optionally use the full-size image if necessary.

Describe alternatives you've considered

The CDN project could be used in combination.

I'll try to get this done by today

That would require either optimized images or on-the-fly optimization on the API side. Which one is being proposed here?
