AJAX jpeg headers

[simon.huntley]

I'm using a PHP script to raw output jpeg files in thumbnail generation. This works fine as completely server-side - I call it through an <img> tag, like <img src='picture.php?width=100&path=test.jpg'> but when I do this through an ajax call it outputs the raw binary data. In a sort of blind attempt to fix the problem, I put:
xmlhttp.setRequestHeader("Content-type", "image/jpeg");

in my ajax script to see if that would fix the problem. Anyway, how do you set the right headers after an ajax call? Can't find the answer in any of my books.

Thanks for any help,
Simon.

I think you did the right thing.
Just put that line in conditional statement and pass a condition when calling ajax function from html element.
