Displaying inline images in HTML email

[beidlerj]

 

Hello,

 

I am attempting to understand PHP's email functions and writing my own simple mail display script.  I have so far been able to snag the HTML part of email messages, but I'm having trouble with inline images contained in a message.  I can figure out which body part contains the image, and I can load the data from the message into a variable, decoding/converting as need be.  What I can't figure out, though, is how to get the image to display in the browser when I echo the HTML message body. 

 

Here's the way I've been approaching the problem thus far:

 

1. Use imap_fetchstructure to get info on a message.

2. Analyze the parts to find body part numbers for the HTML and the image(s).

3. Echo the HTML to the browser.

 

The HTML sent to the browser contains <img src="cid:bunchanumbers">.  How do I get the image to show up in that spot?

 

Thanks muchos,

 

Jeff

If I simply output the file using readfile() or something like it, how does the web browser know that the data is for use as the cid:blahblah image?  I know I could use header() to add "Content-Type" image/whateveritis", "Content-Disposition: inline", etc., but what should I use in the "filename" parameter of "Content-Disposition"?  Would it be the actual name of the file, or the ID parameter, which is referenced in the HTML code (<img src="cid:blahblah">)?

 

Thanks, hope someone can help.  Much appreciated!

Create a file, showimage.php or something like that. Bass the image name via get and pull the file from the db and for the img tag use this:

 

<img src="showimage.php?image=test.jpg" />

 

The showimage.php file should produce proper headers and use the readfile() command.

 

see www.php.net/headers not the user comments, as this has been done many times in there.

Thanks for the reply.

 

Actually, I'm looking for a way to display messages that are read from an IMAP server, without needing to dismantle/store the various parts in a database.  Just read and display, like any ol' webmail.  I tried looking at the code for a few apps like SquirrelMail, but couldn't make heads or tails of it.  It's pretty complex.  I just want to do something very very simple, so I can understand how it works.

I figured out what you were getting at, a couple days after the fact.  Must have been short on sleep then...

 

I was able to get images to display without storing them first.  Just did a simple show script that kicks out the content-type header and the image, but can be referenced in the <img> tag as the source... basically like returning a file, but just a stream of data.

 

Thanks for the help.
