Image produced by FujiFilm 4900Zoom

Examples of error messages. The number of bytes in the error messages varies from image to image.

With an image taken at 640x480 I get error:
Fatal error: Illegal thumbnail size in E:\MyFiles\web\rucc\oldtest.php on line 12

With an image taken at 1280x960 I get error:
FATAL: emalloc(): Unable to allocate -266076160 bytes

With an image taken at 1600x1200 I get error:
FATAL: emalloc(): Unable to allocate -1222377472 bytes

With an image taken at 2400x1800 I get error:
FATAL: emalloc(): Unable to allocate -500891648 bytes

It would appear that it is falling over in function 'ExtractThumbnail' that can be found in exif.c

I have tried the same php script with an image taken by an Olympus camera and it works without problem.

All the other Exif reading utilities I have work equally well with Olympus and Fuji images.

Some sample images
640x480 - http://marct.com/DSCF0023.JPG
1280x960 - http://marct.com/DSCF0022.JPG
1600x1200 - http://marct.com/DSCF0021.JPG
2400x1800 - http://marct.com/DSCF0020.JPG

Sample Script:
<?php
$exif = read_exif_data ('DSCF0023.JPG');
?>

I am using the pre-compiled version of PHP, 4.0.6 with IIS5.
The only change I have made to the php.ini file it to un-comment the line 'extension=php_exif.dll'

I would be of great benefit if I could use this php function with these images and will help in any way I can to fix the problem.

Thank You

Marc
