1706212 - Remote image (jpg) from RSS feed > Save image as... offers only html flavor and is wrongly saved as image (jpg) file with htm/html extension.

Status: NEW

(Thunderbird :: General, defect)

Description

[aeioudev]

Attachment: Screen+Recording+2021-04-20+at+02.56.36.74+AM.mp4

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Tested with Thunderbird 78.10 x64 on Windows 7 and 10 (1809).

1. Add https://vc.ru/rss/all to "Blogs & News Feeds" subscriptions
2. Select any post with an attached image and save it via right click -> "Save Image As..."

Actual results:

The image is saved as an HTML file, but it is actually a full-size PNG. I also recorded a video of this happening with the post view inside the client (latest version of Firefox saves the file correctly).

Expected results:

The image should be saved with the correct name and extension (like "7dafabc0-1274-5bc7-9260-ca5b3df7e5a0.png").

Why does the attachment pane show them as Part 1.x depending on the number of attachments in which post you read and the source shows them like this?

Try copying the image and pasting it into the desired location.

That worked for me.

Hey aeioudev, thanks for well-formed bug report and screencast.

Confirming exactly as described.
Feed source has this:
<img src="https://leonardo.osnova.io/e8069eb5-7fbc-59e1-b79f-da78233be691/-/resize/1300/" width="1280" height="688" alt />
Image shows correctly in feed, image context menu shows correctly, Save Image As... offers only html flavor and adds wrong htm/html extension to the actual image file. Same image directly from FF browser saves correctly.

Workaround: add .jpg extension while saving, or rename image.html to image.jpg on your disk.

Shouldn't there be a filename in the source code?
