when reading an inline forwarded html email no "show images" button is shown to
allow the reveal of the blocked images.

Reproducible: Always

Steps to Reproduce:
1. inline forward an html email (my test email was an eticket from an airline)
2. view message and note lack of "show images" button

Actual Results:  
the email contains the html img tags and thunderbird properly blocks the images,
but no "show images" button is given to reveal those images.

Expected Results:  
i would expect a "show images" button per normal behavior for html email.

Images are normally not blocked if the sender (in this case, you) is listed in 
the address book.  Is that the case here?

How do the blocked images appear?

Had images been unblocked (sender whitelisted) on the original message?

The usual complaint is that when forwarding an HTML message with remote URLs for 
its image tags, the images are included (as MIME parts) in the message, rather 
than maintaining the remote URL (bug 176416).  For inline-forwarding, this has 
been changed recently due to a potential security issue; that's bug 303752 (not 
publicly accessible, but described at bug 305557 comment 4).

I've just run a test, and if I forward from my regular account (which is listed 
in the address book), the (remote) images are displayed; if I forward from an 
alternate, unlisted account, the images are blocked but the "Show Images" button 
is available.  This is with 1.6a1-0904, Win2K.

my configuration has no entires in an addressbook, i use ldap exclusively.

the blocked images appear like any other blocked image, as a placeholder.

i had revealed the images before forwarding, yes.  my compose window showed the
images as they were in the original email.

interesting....i tested this on my win xp and mac osx using version 1.6a1
(20050907) on both and got no "show images" button.  i've attached the resulting
email (cleansed a bit only for content).  i'll also try 20050904 and see if that
worked.

just tried 1.6a (20050904) and got the same results.  i wonder what i'm doing
differently.  i can forward you the same email to see if you see the images if
that would help.

ah...interesting.  i've tried other html messages and they work fine.  it seems
to be something specific to this one particular email -- my bad for not being
more thorough on checking.  it'd be interesting to figure out what's causing
this one message to break, but it might not be a huge problem.

Sure, that would be fine; or, if it's not sensitive, save it as a .EML and 
attach it to this bug (use the Create New Attachment link above).

I just read the coments regarding blocked images without having the ability to view them, but I found no way of correcting this problem. I get photo's from my children and I cannot view them. How do I install a buton or a menu option to "Unblock images"?

Obviously when I made this comment, I'd managed to miss that you had already made an attachment here.  I just loaded that message up, and you're quite 
right: the Show Images button doesn't display.

I tried editing the message to remove the 'moz-do-not-send' attributes from the images, and that made the difference.  I had to remove *all* of them, but once I had done that and reloaded the message, there was the Show Images button.

I don't get the Show Images button even if I remove the moz-do-not-send attributes in the file.
I only get the message that linked content was not loaded due to security settings.
