Blank image error

["Paul Buder" <paulb@xxxxxxxxxxxxxxxx>]

Squirrelmail is replacing images with blank images in some cases. This is due to the image not having a file extension squirrelmail recognizes. In particular, I am dealing with email that has images with the following form of url.

 

<img src=""

 

And the code in functions/mime.php lines 1750 and 1751.

 

                                    if (!in_array($ext,array('.jpeg','.jpg','xjpeg','.gif','.bmp','.jpe','.png','.xbm'))) {

                                        $attvalue = $sQuote . SM_PATH . 'images/blank.png'. $sQuote;

 

Since the image is getting served up by a cgi script squirrelmail replaces it with a blank. I am no expert on html specs but I thought extensions were supposed to be ignored in favor of content-type in the http header. What do you all think?

 

 

Configtest.php follows.
