Red X instead of image in some Browsers?

[a10]

Hello, 1st backup index.php. Using a good editor (notepad++) remove

header('X-Content-Type-Options: nosniff');

upload index.php and see how it goes. Worked fine here.

I think that someone made a little script to update  the db

Would also be interested in this.

You have, however, removed a security protection by doing so...

^^^ nosniff line had to go, as thousands of perfectly normal pictures (+ many avatars) from my 1.x forum turned into red x's in IE after upgrade to 2.x, result was a crippled forum for all IE users. As it stands now, 'nosniff' + IE = attachments with zero security issues are treated as if there is some issues. Is this a IE or SMF problem, or what is going on exactly? Thanks.
