Seemingly valid image URL not loading

[jeffreyameyer]

Bug description What is happening? -

• On this way, https://staging.openhistoricalmap.org/way/198291609
• For this tag: image:3 = http://pcad.lib.washington.edu/media/pcad-images/2265.png
• Getting this error:

What should be happening?

• Should be seeing the image at that link...

Interesting. What I notice is that both of the images that work are https in the tag value. This one is http. And we're passing that through correctly it seems:

But if we look in the network tab, we're actually asking for https:

And try that link with https and you get this:

Take the s away, works fine. But if we solved for using actually http here in the img request, we'd end up with mixed content and get blocked by browsers as a security threat. I am a bit surprised that http://pcad.lib.washington.edu/ doesn't use HTTPS anywhere far as I can see. Including on their login page, http://pcad.lib.washington.edu/admin/login/

That's not our problem, but one of the challenges of pulling images from various places on the web is that we're likely to end up with either (a) an error like this or (b) mixed content and therefore SSL warnings

@dan - would it make sense / be possible to show an error message on a failed image load attempt?

Whatever this problem was, it doesn't seem to repro here or there was a workaround & it's been open without comment for almost 2 years. Closing.
