1544657 - images in Templates saved to subfolders causes "Thunderbird has blocked a file from loading into this message."

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[sinstr69]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

Creating new email from a template is fine if template is directly in Template folder.
However (for organizational purposes) template is saved in a subfolder of Templates folder the images (in signature) report as being blocked and cannot be unblocked.
Using an Exchange shared mailbox/Imap

Actual results:

Thunderbird has blocked a file from loading into this message. Unblocking the file will include it in your sent message. Clicking options and unblock fails

Expected results:

unblocking should work or as per templates not in subfolders are not blocked to begin with

Sorry for the delay here. How does the template actually reference the image? Using a file: URL or a http(s): URL? Maybe you can view the source of the template and copy/paste the image information here.

in the above email the signature picture is working, but if I was to move this into a sub-folder of the templates menu the picture is broken

Please don't paste message content into comments. Attach the .eml file instead using "Attach File" above.

Here's the message. I had to correct the encoding in the part header to UTF-8. Like this, it displays fine. I don't see an issue if the template is moved into a subfolder of Templates, but then, I'm not using IMAP right now. However, the linkage is from <img id="Picture_x0020_1" src="cid:[e-mail]" alt="Gipps Wifi Logo EDITED" class="" width="244" height="73"> to the image part

Content-Type: image/jpeg;
name="image001.jpg"
Content-Transfer-Encoding: base64
Content-ID: <[e-mail]>
Content-Disposition: inline;
filename="image001.jpg"

and that should always work. I'll try IMAP in a minute.

Hmm, no difference when using IMAP. Template displays fine in subfolder and "New Message from Template" also works. You're really using IMAP or are you perhaps accessing your Exchange server via a 3rd-party add-on like Owl or ExQuilla?

Attachment: This is the original working email.

Not using 3rd party exchange client.
This when moved into sub-folder makes the picture break.

Attachment: Example of a broken image email

this is an emial that had the missing picture copy and pasted in. When I created it it seemed to work, but after sending this is what is left in the sent items folder. Not sure if it is related but hope it helps.
I will attach a copy of the other email with broken signature when
I get back to work.

I don't know what the problem is or how that relates to templates, or templates stored in subfolder. The message "Example of a broken image email" displays fine for me after unblocking the remote content which comes in from https://www.groovypost.com/wp-content/uploads/2017/04/OOBE-2-640x480.png

    <p><img class="lazy alignnone size-medium wp-image-107143

        1026w" data-lazy-sizes="(max-width: 640px) 100vw, 640px" width="640" height="480"></p>

Or that exactly isn't displaying correctly?

Sorry It had been some time since I looked at this issue myself.
As mentioned in previous reply unblocking should show the picture.
The I ssue I have been finding is that when the template is in a subfolder the unblock crashes and does nothing except prevent the options button from responding again.

This comes from blockedContentMessage https://searchfox.org/comm-central/source/mail/components/compose/content/MsgComposeCommands.js#8825

Why we would relax this for a message that isn't in the templates folder?

I have the same issue: images in sub-folder templates are blocked. Clicking option then unblock on yellow alert message does not solve problem.
My personal observation re this bug is in 'image properties' with a location changing from 'data:image/png;filename=etc...' working properly to 'imap://info%40 etc...'

I have attached screenshot

So the question is : why images are blocked and change of location when you move message from templates to a sub-folder template?

It is just annoying in term of time waste as you have to insert a proper image every time you use a template stored in a template sub-folder. Meaning that it is impossible to sort our templates in different subfolders

Many thanks
