Detection api in v4

Old threat but I think I need to do a similar analysis.

I want to download all advertisements (only the ads, not the whole street picture) in image format (preferably jpg) in a 500m radius around a certain location.
When using the web app I can only download the location in shp, GeoJson, ect format.
I have very limited programming knowledge and the code in this thread is too complex for me. Is there a comprehensive tutorial where this process is explained step by step ?

Thanks
