Viewing .jpg Pictures in Thunderbird

[Jim]

FC 10/ KDE

I have one person that sends me .jpg pictures in a Email and thunderbird 
can not display them ,  when I try to Open them I can only "Save" them 
to my Picture folder to view them. That person uses WindowsXP.

I recieve .jpg pictures from every one else and I can view them in 
Thunderbird.

What could it be ??

The MIME type declared in the e-mail is incorrect.

So what your saying is that the Mime type setting in her Outlook
is wrong ?

How would she change that in Outlook ?

have a look at;
  https://addons.mozilla.org/en-US/thunderbird/addon/2307
which may handle problem.

main problem is as kevin is telling you, if mime type is written wrong in
email, thunderbird will have problem knowing what to do with attachment.

use <ctrl+u> to look at full email. you should have below message body
something similar to;

|>  --------------090209040005060100010505
|>  Content-Type: image/jpeg;
|>   name="tbird app local folders.JPG"
|>  Content-Transfer-Encoding: base64
|>  Content-Disposition: inline;
|>   filename="tbird app local folders.JPG"

this is how thunderbird knows that attachment is a jpeg file.

being that sender is using ms xp, there is your major problem. ms does not
comply with email rfc. if sender does not has file with a '.jpg' extension,
ask them to try sending with extension name.

I think this may explain it here. Every picture shows this Content-Type

Content-Type: application/octet-stream;
    name="ATT00049.gif"
Content-Transfer-Encoding: base64
Content-ID:

Thanks guy for your help I learn something new today.
I could say in about 50 years I would know everything there was about Linux, to know it all.

NOT!!!

that will squirrel the bird.

something you could 'try for the fun of it'. cerate a new subfolder and
*copy* email to it.

close thunderbird and then with a _plain_text_ editor, vi, kwrite, etc,
open email and change 'application/octet-stream' to 'image/jpeg'.

delete '.msf' file associated to subfolder and delete 'panacea.dat' in
your profile directory, '/home/jim/.thunderbird/????????.default/'.

reopen thunderbird and it will rescan your folders. then open email and
click attachment to see if it will open as a '.jpg' file.

i have done a lot of things to modify thunderbird emails, but never
tried above. it may work. it may not. if not, it is problem with
'octet-stream' coding attachment differently from what an 'image/jpeg'
would be.

Didn't you say it was a JPEG file? Those headers are for an
undifferentiated binary file whose name implies it's a GIF, which isn't
the same thing.

Your problem has nothing to do with Linux. The sender's email
configuration (or host platform) is broken. They may not think it's
broken if their Windows-using friends can see the images in messages,
but it's still broken.

correct on gif. i did not realize i i told jim;

until i read your post. i guess too much reading of '.jpg' in his post.

it should have read;

|> open email and change 'application/octet-stream' to 'image/gif'.

as i stated, i do not know how thunderbird will handle such a change
because graphic files do have type embedded in first 9 bytes of file.

in fact, just to see what would happen, i sent my self a '.gif ' file
and changed '.gif' to '.jpg'. thunderbird showed '.jpg', yet it did
display correctly inline.

so, how ever thunderbird is reading file, file itself is being used to
determine how to be displayed.

therefore, i tend to conclude that ms email client may be doing more to
hide file type.

he said they are using windows. it is not broken, it is just another case
of msbsos doing things 'their way'. 'the world is wrong. ms is right.'

Thunderbird is seeing the Attached pictures as .jpg, I noticed the .gif 
extension in Content.
You know how Windows users are, they will not admit they have problems, 
it's that damn ole Linux.
