Problem when trying to display image from database

[eluser]FabD[/eluser]
I applied the proposed code ... but still no image displayed.
It seems that it doesn't reach the function displayimage()

In the form/view, I have changed the call to the function displayimage() by a dummy call to an undefined function 'toto' :

Code:

<img src="&lt;?php echo base_url() ?&gt;index.php/signal/marches/toto/&lt;?php echo $marches['MA_ID'] ?&gt;" border='0' align='left'/>;

or

Code:

<img src="http://localhost/gerico/index.php/toto/1" border='0' align='left'/>

and .... nothing happens, no errors reported. So it seems that CI ignores the call into the 'src' parameter of the image ...

Any ideas ? where do I have to put the call to display the image ? Is my way of working wrong ?
