    EXIF Thumbnails

    I'm trying to display the thumbnail contained within the EXIF data of a picture file using the following code:

    $testthumbnailimage = exif_thumbnail([file path and name],$width, $height, $tempType);
    echo $testthumbnailimage;


    This code produces nothing. But if I remove the ,$width, $height, $tempType section from the first line, the following is displayed on my page:

    I added
    header("Content-type: image/jpeg");
    to the top of my page, but still no luck.

    I was able to extract and display EXIF info about the file (comments and such), and would like to utilize the embedded thumbnails to make my life easier.

    Thanks!

    did you set the header type ??

    $testthumbnailimage = exif_thumbnail([file path and name],$width, $height, $type);
    header("Content-type: ".image_type_to_mime_type($type)); echo $testthumbnailimage;

    ?
    resistance is...

    MVC is the current buzz in web application architectures. It comes from event-driven desktop application design and doesn't fit into web application design very well. But luckily nobody really knows what MVC means, so we can call our presentation layer separation mechanism MVC and move on. (Rasmus Lerdorf)
