Image Display/Save As problem

[mmcb]

I have 2 problems with displaying images directly to the browser:

1) I have worked out how to display the image:
[code]$filename='testimage.jpg';
header ('Content-Type: image/jpeg');
imagejpeg($filename);[/code]

No problem there, it works great, the image is displayed just as it should be. But, when I try to save the jpg image I can only save it as a BMP file!! For some reason the browser doesn't recognise that it is a jpg file. It is happening to other people as well, so it's not a local computer problem.

2) My second problem is that the displayed image (when saved) is a different resolution to the original. The original image has a 300dpi resolution. Why does this change when the image is displayed in this style?? When I use a normal IMG tag to display the jpg it retains the 300dpi resolution.

Any help would be greatly appreciated as this is driving me nuts ???

I'll take it that no-one can help me with this then.........*sigh*

Try

$filename='testimage.jpg';
header ('Content-Type: image/jpeg');
readfile($filename);

[mmcb]

I tried that already and it still doesn't work. It displays the image fine (same as imagejpeg does), but I still can't save the image as a JPG.

try

$filename='testimage.jpg';
header('Content-Disposition: inline; filename="'.$filename.'"');
header ('Content-Type: image/jpeg');
readfile($filename);

*sigh* Nope, that didn't work either :(
Could it have something to do with the server configiration or am I just clutching at straws here?

whilst it might not solve the problem, lets try getting things into the "normal" way of doing things. [url=http://uk2.php.net/imagejpeg]imagejpeg[/url] (function) takes 3 parameters - the 'resouce', a '[b]destination[/b]' filename, and a 'quality' setting.

[code]
<?php
$im = imagecreatefromjpeg('testimage.jpg');

header('Content-type: image/jpeg');
imagejpeg($im);
?>
[/code]

the default quality setting for imagejpeg is 75%. if you want higher, use (for example)

[code]
imagejpeg($im, '', 90);
[/code]

have you tried this on a different browser yourself, just to make sure that its not an issue of what the browser is set to accept?

what browser are you using if you can only save it as a bmp file

[mmcb]

I've changed the code to:
[code]$im = imagecreatefromjpeg($filename);
header('Content-type: image/jpeg');
imagejpeg($im,'',100);[/code]

Where $filename comes from a MySQL table.
I've tried it in IE6 and Firefox, both browsers display the image perfectly. However, IE only lets me save it as a BMP file. Firefox on the otherhand wants to save the php file (downloadimage.php). If I try saving it as a .jpg it won't open in graphics programs. However, atleast with firefox I have the ability to copy image which works.

Am I missing something or what? I've been through all the tutorials I can find and they all seem to work.

How are you trying to save it? Right click and...

[mmcb]

Yep.
Right Click, save image as.......

In IE I get:
Filename: untitled
Save As Type: Bitmap (*.BMP)

In Firefox I get:
Filename: downloadimage.php
Save As Type: All Files
