yesterday I created a simple "quote of the day" script for my google site. The script reads the quote from a google sheet. I also wanted each quote to go with a companion image, which I host in my google drive (the image Ids also are stored in the sheet).
I followed the instructions explained here, and everything seemed to work fine. The permissions for the images was "everyone with the link within my institution" (this is supposed to work in a website on the google apps for education).
It was a success, because the images did display correctly.
Today I opened that page again, and the images have disappeared.
I know that image hosting was discontinued in 2016, but I think it was a different way of hosting (no permalink). Indeed, as I mention, yesterday I could see the images in the website.
Also, when I write the "permalink" in chrome address bar I get "403. That’s an error. We're sorry, but you do not have access to this page. That’s all we know." This happens despite I'm the owner of the file, and I'm logged in the correct google account. Also, it happens irrespective of the browser and/or machine I use (I tried with my phone too).
I also tried what explained here, although I'm not sure I understand that completely. There should be a problem though, because instead of the image I get the alt text (NA).
Is the "permalink" method still supposed to work? Could this be a problem of excessive traffic? I haven't even published the page yet, I only did some testing...
What is the best way of displaying images from google drive into google sites, without resorting to third party services?
Thanks a lot
