Image not showing up in pop-up in web map

Question

I am creating a web map with locations which have pictures attached to them. I have a CSV file with the locations and their thumbnail url and regular-sized photo url, which I took from Flickr. They are shared publicly. I created a shapefile from the CSV file and then added to a web map. I followed this link to customize the pop-ups to show the thumbnail image:

But my thumbnail shows up like this (when I click on it, it directs me to the the regular-sized photo in Flickr).

I am not sure why the thumbnail image does not show up.

Hello!

I have a similar problem, but it is more likely due to a lack of understanding of how to set different URLs for different lines.
There are more than 900 positions in my table, each of which needs its own photo, I have my own photos, but even by setting test URLs I was only able to set one image for all rows. How to make pictures individual?
How can I download them from my computer?
This is ArcGIS Pro

Thank you very much..
