PHP thumbnail generation and IE Save As

Last Modified: 2010-07-27
Hello guys,

i have made an img.php that generates thumbnails for my images, and resize big images to 640x480.
i use

header('Content-Disposition: inline; filename=' . $fn); //$fn stands for file name

to save images with their original names while using Save As.

But when i add the images into another page using img tag or iframe it Save As doesnt work as expected. It tries to save as untitled.bmp

Here are 2 URLs one to a pop up page. and one to the image itself.

I have read a few articles to prevent IE saving images as untitled.bmp but they did not work.
what can be wrong?

Using IE I get the same behavior you described, in an img tag it just calls itself image.bmp. FireFox does rename it well in both ways.

Did you add
header('Content-Type: image/jpg');
(or was it image/jpeg)
to your code? That should at least get rid of the bmp thing

Thanks for your reply.
its already  image/jpeg :)
i am just reading a jpg file from a directory and output it to browser via
 ImageJPEG function.

What about content-disposition: attachment?

i tried that before. when img.php is used as an iframe it tries to save the file with the correct name :) but it doesnt make any differance in image tag. I think its something with IE reading image source headers, because it works correct in most browsers except IE.

Oh no, I didn't read the original question right, sorry.  

'Save as' on an IMG element resulting in untitled.bmp is definitely not a server issue. Try clearing your temporary internet files first, then reset web settings.

http://support.microsoft.com/?kbid=260650 - Temporary Internet Files folder is full or you are using HTTPS and the images are not cached.  Possibly your images are not cached anyway using HTTP response directives like "pragma:no-cache" etc.

If the original file is not cached, all IE will have is a bitmap representation.  Other browsers ignore pragma:no-cache.

http://support.microsoft.com/?kbid=810978 - May also be the result of a damaged plug in.

So, what http headers are being returned for that Image?  You'll need to use a tool like http://www.blunck.se/iehttpheaders/iehttpheaders.html to prove.
