Images and fpassthru

Hi,

I am pulling images from my webserver.

I have tried two alternatives for sending them to the browser, fpassthru and ImageJPEG (using GD).

Here is my problem:

fpassthru always gives me BMPs (when trying to save them, the browser claims they are, at least)
ImageJPEG creates images where the quality differs from the original, or the images are much bigger in size...

Here is the code I used for fpassthru:

header( "Content-type: image/jpeg\nContent-Disposition: inline;filename=\"mypic.jpg\"\nContent-length:".(string)(filesize($filename)) );

$fp=fopen($filename, "rb");

fpassthru($fp);
flush();

And: no, I can't simply do an "echo <img src="pathtothefile"> sort of thing, as I need to restrict access to the images..

Any ideas? Does fpassthru always put out bmps or am I doing something wrong?

I appreciate your help.

fpassthru outputs the file 1:1, no conversion at all. If the source is a BMP, the image will be BMP, if the source is JPG, the image will be JPG.

(using useimageJPG makes no sense)

I take it you are reading the image files from a directory somewhere outside the documentroot?

That's right. They are outside the documentroot.

But, as I restrict uploads of images to jpegs/pjpegs the files on the server just got to be jpegs.

Still, when I right-click and save them, I only have bmp as an option.

Strange...

Maybe I could use imageJPEG and determine the original jpeg quality, thus preserving file size. But how?

Or can you maybe think of what I am doing wrong with the fpassthru?

Or have a reliable code that I could adapt?

Thanks for your help! 🙂
