Image not displayed in sidebox with ie 7.0 (ZC 1.3.7)

Any help with a strange bug (?) :
With IE7, image in sideboxes banner_box and banner_box2 are not displayed.

Hereafter is the html code of the page :

<!--// bof: bannerbox2 //--> <div class="leftBoxContainer" id="bannerbox2" style="width: 150px"> <h3 class="leftBoxHeading" id="bannerbox2Heading">Livraison</h3> <div id="bannerbox2Content" class="sideBoxContent centeredContent"><a href="http://www.retrodeco.fr/index.php?main_page=redirect&action=banner&goto=11"></a></div></div> <!--// eof: bannerbox2 //--> <!--// bof: bannerbox //--> <div class="leftBoxContainer" id="bannerbox" style="width: 150px"> <h3 class="leftBoxHeading" id="bannerboxHeading">Paiement sécurisé</h3> <div id="bannerboxContent" class="sideBoxContent centeredContent"><a href="http://www.retrodeco.fr/index.php?main_page=redirect&action=banner&goto=9"></a></div></div> <!--// eof: bannerbox //-->

Thanks for your help

They show up without problem in my IE7. This may be something to do with your specific version of IE7 and its settings.

Yes,

When you look at the html code generated you can see that <img...> are not there! As if they had been filtered by... IE7?? Is it possible?
