Description:
------------
Purpose: upload images, store in db, write to PDF.
Problem: some JPEGs consistently fail on a getimagesize()
Error: "Warning: getimagesize(): stream does not support seeking in /www/phototest.php on line 47"
Replicable: Yes.  I receive the same results on RedHat9 with PHP 4.3.10 and Debian (Sarge) with PHP 4.3.10-9
Config changes: I can only specify the Debian setup.  Fresh setup, only the document root changed.

Test photos came from the same camera and were taken within minutes of each other.
Photos are available at:
Error	
http://www.clanlineage.com/temp/IMG_0086.JPG   (132kb)
Success	
http://www.clanlineage.com/temp/IMG_0087.JPG   (113kb)

The included class is from other authors, so I have credited them in the code.

Reproduce code:
---------------
http://www.clanlineage.com/temp/phototest.txt   (2kb)



Expected result:
----------------
Using JPEG image IMG_0087.JPG

Array ( [0] => 1024 [1] => 768 [2] => 2 [3] => width="1024" height="768" [bits] => 8 [channels] => 3 [mime] => image/jpeg ) 


Actual result:
--------------
Using JPEG image IMG_0086.JPG

As the message says: Your stream doesn't support seeking 
so you need a stream_seek method...

I started reading up on streams (and classes) last night.  I wouldn't have posted but I thought with images from the same camera, what worked for one would for all.  I cut and pasted the sample code on the link you provided and it worked.

Thanks for the quick reply and sorry to have bothered you.
