do it in the getter of the image.
public getImage(){ return Base64Encoded bytes }
<image src="each.image></p> ">
Something like this:
zul:
<image src="@load(vm.imageAsBytes)" width="100px" height="100px"/>
ViewModel:
public String getImageAsBytes() {
String s = "data:image/jpg;base64,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";
