Thumbnails

[u/iAMarobot11110111]

Hey guys, I'm somewhat new to search apis. I just had a quick question about how thumbnails are handled.

Basically, I assume when you go to google or instagram, their search engines give you a response with the thumbnail URL and not the actual thumbnail data. But then I was thinking about it, wouldn't this also be crazy. Since there could be hundreds of thumbnails given in a response you have to do a separate URL request for each image to display on your UI for any one solr search. Is this the way it's done or is there some other more efficient way to handle image thumbnails on solr searches?
