Calendar event photo attachment display without downloading

Is it possible to have the photo attachment (specifically on a calendar event) display on the pop-up without having to download the photo/file to view it?

It would vastly improve the user experience to just see the photo right away and be able to make a decision rather having to download the file to see the photo.
Thanks in advance!

I am bout to begin implementing calendar block, but maybe you can try ‘embed’ (not sure if it is available) for the file type and display your image ?

I am not sure how either but it works in a list or table block so it probably could also work in the calendar block.
