Problem when trying to display image from database

[eluser]FabD[/eluser]
I finally captured an interesting error:

Code:

<h4>A PHP Error was encountered</h4>

<p>Severity: 4096</p>
<p>Message:  Object of class OCI-Lob could not be converted to string</p>
<p>Filename: signal/marches.php</p>
<p>Line Number: 88</p>

thats the line : print($image) ;
