page layout &web part

Hello everyone ,

I have created a pagelayout with webpartzone in it. 

in my pagelayout, i have a list item which is ;

<SharePointWebControls:ListItemProperty  runat="server" id="ListItemProperty2" List="{mylistid}"  Property="PublishingRollupImage"/>

i can see my image in this way but, 

if I add my web part (which is not related with the list imagefield, its only a button) i cant see the image. 

it removes the 

<img alt="" src="/SiteAssets/img_1.jpg" width="134" style="BORDER:0px solid;">

any suggesstions?
