Actual results: I tried to enable "show remote content", but this option has no effect. I see in the v. 52 release notes to enable "ail.compose.attach_http_images" - but have no idea where this is supposed to be done (command line? file?) Expected results: Images should have been displayed all along.
We really can't action "Images stopped showing up suddenly" :-( This report doesn't have any detail whatsoever. Where did images stop showing up? When you view a received e-mail that contains embedded images? Maybe not. As you know reading the release notes, we've made change to how images are included in a new e-mail composition. So is that where the problem is? Perhaps an image in the signature? Please note: Bugzilla is NOT a support forum. It is a tracking system for bugs in Mozilla products. This is a support question. You can get support here: https://support.mozilla.org/en-US/products/thunderbird I've seen a bazillion bugs related to the new behaviour, and they were all invalid, so is this one. That said, if you give us some minimal details, we might be able to assist you.
I consider this a bug! Images suddenly stopped showing up in the viewer pane - in spite of the "Allow remote content" option being checked (Tools\Options\Privacy\Mail Content). I made no changes to options, and can't seem to change this (even by unchecking that option, restarting, checking it again, restarting...) This applies to all images, on outgoing and incoming e-mails. Finally, there is nothing on your support forum to address this issue, nor any instructions where to include the "mail.compose.attach_http_images" string.
The preference "mail.compose.attach_http_images" has to do with attaching images from http(s) resources that you include in an e-mail you're writing. It can be set in Tools > Options, Advanced, General, Config editor. But that has nothing to do with your problem. You're saying that you can't see images when viewing messages despite "Allow remote content" being checked. First you need to understand how images in HTML e-mail work. Some of them are attached to the e-mail, others are fetched from the internet when viewing the message, that's the "remote content". Can you run TB with all add-ons disabled (see Help menu) and check whether the problem persists. And no, it's not a bug so far since this is the first report I've seen.
I tried running in safe mode, but nothing has changed. Attached images aren't shown (just a text string when an image is attached, or hyperlinks for remote content). Funnily enough, on another computer I have the same problem in Chrome! Images won't display in GMail or Google Photos.
Are you sure you haven't accidentally set: View > Message Body As > Plain Text? What you wrote in comment #3 is really weird: "just a text string when an image is attached, or hyperlinks for remote content". Can you upload a screenshot? Use "Attach File" above.
I've attached two screenshots, one with remote content and one with local content.
(In reply to Jorg K (GMT+2) from comment #5) > Are you sure you haven't accidentally set: View > Message Body As > Plain > Text? Did you check this option?
Funnily enough, some photos were displayed correctly, though not others. I looked, and indeed that setting had been changed. Perhaps toggling it back and forth (as well as inserting the "mail.compose.attach_http_images" string) seems to have resolved this. Thanks for your help!
