This code does not work :
<img class="icon" src="{resolver:resolveImage('explorer', ametys:resourcesByPath('CharteGraphique/Nouveaut*é*s')/resource[@name ='concours.png']/@id,23,0)}"/>
This code works :
<img class="icon" src="{resolver:resolveImage('explorer', ametys:resourcesByPath('CharteGraphique/Nouveautes')/resource[@name ='concours.png']/@id,23,0)}"/>
