539846 - HTML images are coming up as attachments

Status: RESOLVED DUPLICATE of bug 525955

(Thunderbird :: General, defect)

Description

[lapinamoureux]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.0.8) Gecko/2009032608 Firefox/3.0.8
Build Identifier: Thunderbird 3.0

When sending HTML inserts or HTML signatures with an image to GMail, Yahoo, or Hotmail accounts, the email is received with the images as attchments. The image displays in the message pane, but all image files related to the HTML are listed as attachments. this looks rather bad when sending professional emails from a business.

This does not occur when using TB 2, but always in TB 3. No changes to the image properties or sending options changes this.

Reproducible: Always

Steps to Reproduce:
1.Open new message
2.Insert HTML containing src images
3.send to webmail account and see the result.
Actual Results:  
web client shows message with option to download attached images.

Expected Results:  
The image should show up as normal in the reading pane and without the webclient showing them as attachments.

That's possibly related to bug 525955 as a regression of switching the default content-disposition from inline to attachment per bug 65794 for TB 3.0.

Go into Thunderbird > Preferences > Advanced > General, click Config Editor. Search for mail.content_disposition_type and double-click on that entry.
Change the value from 1 to 0 and close all preference windows.

If this change resolves your issue, this indeed was caused by the wrong image content-disposition of attachment (= inline after that modification).

You are welcome, I'm re-resolving this as a duplicate though.
