the example shown were loaded during onEvent, assume that i can get the
image loaded with inputstream and return as StreamResponse; upon changing
selection as this for my t:select component

@InjectComponent private Zone showPictureZone;

@OnEvent(value=EventConstants.VALUE_CHANGED,component="packageSelection")
public Object onPackageSelection(PackageObj theObj){
//Read Image as streamresponse and generate a url link and embed inside img
tag
return showPictureZone.getBody();
}

how do i create a url embed inside <img src/> ?

the tml is as follow:

<t:select  t:id="packageSelection" t:model="cnbfSelectModel"
t:blankLabel="please select" t:blankOption="always"
 t:value="selectedPackType" t:encoder="le2uProductEncoder"
zone="showPictureZone"/>
<t:zone t:id="showPictureZone">
    <img src="${???}"/>
</t:zone>

please advice,
