When adding an image from the Add variable popup in the container page we generate this code

#if (${imageImageURI})
   <img src="$!{imageImageURI}" alt="$!{imageImageTitle}" width="$!{imageImageWidth}" height="$!{imageImageHeight}">
#end


we need to close the image tag like this />

#if (${imageImageURI})
   <img src="$!{imageImageURI}" alt="$!{imageImageTitle}" width="$!{imageImageWidth}" height="$!{imageImageHeight}" />
#end
