Image MIME/file type

[Vertuas]

Hi All,

Is there a way to get PHP to change the mime type for a file sent to a
browser.

I need my website viewers to be able to click a link to directly download
and save an image, rather than the browser displaying it.

Is there some other way to make this happen?

Thanks

David

Look up Content-Disposition, but don't hold your breath.

Hi John

The images are purchased by the user, having them go through an instructions
page for there browser telling them to right click and save as an all that
i't would be nicer if they could click a download link, give it a name and
job done.

Trouble is linking to the image results in the browser displaying the image,
rather than downloading it.

Thanks for the reply.

You need to send content-type and content-disposition headers, example:

header('Content-type: image/png');
header('Content-disposition: attachment; filename="'$filename'"');

Thanks again guys

I found this code on php website

$f = fopen("file.txt", "rb");
$content_len = (int) filesize($f, "file.txt");
$content_file = fread($f, $content_len);
fclose($f);

$output_file = 'MXimage.jpg';

@ob_end_clean();
@ini_set('zlib.output_compression', 'Off');
header('Pragma: public');

header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate'); // HTTP/1.1
header('Cache-Control: pre-check=0, post-check=0, max-age=0'); // HTTP/1.1
header('Content-Transfer-Encoding: none');
header('Content-Type: application/octetstream; name="' . $output_file .
'"'); //This should work for IE & Opera
header('Content-Type: application/octet-stream; name="' . $output_file .
'"'); //This should work for the rest
header('Content-Disposition: inline; filename="' . $output_file . '"');
header("Content-length: $content_len");

echo $content_file;
exit()

the filename MXimage.jpg is my own test image file.

when i point IE at it, i get a message about a 3 byte HTML file. Why does
that image file not come through? It seams that the script doesn't even pass
the image data on.

is this something to do with the way PHP handeles the headers. Its running
on a Linux host.

Thanks again
