This is what I was looking for I think..  But it still gives me an 
error..  This one actually got inserted right into the database:

<br> <b>Warning</b>: Data is not in a recognized format. in 
<b>/home/mike/wtoaction/public_html/caravan2001/edit_image_handler.php</b> 
on line <b>65</b><br> <br> <b>Warning</b>: Supplied argument is not a 
valid Image resource in 
<b>/home/mike/wtoaction/public_html/caravan2001/edit_image_handler.php</b> 
on line <b>34</b><br> <br> <b>Warning</b>: Supplied argument is not a 
valid Image resource in 
<b>/home/mike/wtoaction/public_html/caravan2001/edit_image_handler.php</b> 
on line <b>40</b><br>

This is these are the relenvant pieces of the code..

Any suggestions would be appreciated..

Mike
