Clicking attached image doesn't show in Mozilla


When you see a case with an attached image, it works fine in IE and Mozilla based browsers, but it you then click on the image, it doesn't show in Mozilla based browsers: you're a missing a

    @header("Content-type: whatever");

in download.php, given than Mozilla does not file sniffing for guessing content-types.

A quick fix for this is using the mime_content_type() function, which has the additional benefit of adding proper support for many other file types.

    if (@function_exists("mime_content_type")) {
        $mimetype = @mime_content_type($filename);
        if (!empty($mimetype) {
            @header("Content-type: ".$mimetype);

You need to enable mime support for this, but with the check from above, it's safe to use it: people with mime support benefit from this, rest of people will have the current behaviour.

You mean because Mozilla prompts you to save the file instead of showing it to you in the browser?

No,  I mean Mozilla-based browsers display garbage, as they do not try to guess the file-type. They rely on a proper content-type header.

Ok, I can't reproduce this.  I need more details on your OS and the exact versions of

* your browser
* php
* httpd
* mysql

Currently the content-type is already set.  If it is not known it is set to application/octet-stream which all browsers will prompt to save.  I think this might be a problem with the mime type settings on your webserver, but I'm not sure.

Oh yes, and what version of fogbugz are you running?

unix fogbugz 3.1.12
Regarding the content-type, octect-stream should be ok (although is would be more desirable to tag well-known file-extensions with the proper content-type, as images), but what i'm gettting is a text/html content-type, which is obviously wrong.

GET /download.php?ixBugEvent=127&sFileName=submenu_stats.jpg&sFile=yes HTTP/1.1

HTTP/1.x 200 OK
Content-Type: text/html

I'd go for my suggested solution with mime_content_type() function.
