Having problems with upload applet - Upload Error

I am having problems getting the upoad to work keep getting this error
when I upload certain files

Upload Error: Upload Failed

and the apache2 error_log is showing

[Mon Dec 27 23:01:51 2004] [error] [client 192.168.1.103] File does not exist: /data/WWW/www/htdocs/gallery2/com
[Mon Dec 27 23:01:51 2004] [error] an unknown filter was not added: PHP
[Mon Dec 27 23:01:51 2004] [error] an unknown filter was not added: PHP

The images comes from a Nikon D70 in Fine (L) mode image size is 2.7Mb
and file shows it as a jpeg... image viewers etc show the image ok.

Also other photos seem to upload ok without error for example I have an
image from an Olympus 480 thats 398k in size, so this would seem to be
a size issue.

I have also modified

/etc/apache2/conf.d/php4.conf

with

<Files *.php>
SetOutputFilter PHP
SetInputFilter PHP
LimitRequestBody 5242880
</Files>

Massive size so this should not be the issue.

Any ideas ?

thanks Jon
