Remove Google Maps iframe address popup
The following works for me. I updated iwloc=A to iwloc=near. You were adding that code in the tag after the iframe, not within the iframe src itself.
<iframe width="295" height="250" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=3904+Washington+Parkway,+Idaho+Falls,+Idaho&aq=0&oq=3904+washington+parkway+idah&sll=41.833733,-87.731964&sspn=0.929078,2.113495&ie=UTF8&hq=&hnear=3904+Washington+Pkwy,+Idaho+Falls,+Bonneville,+Idaho+83404&t=p&ll=43.466874,-111.993513&spn=0.015573,0.025406&z=14&iwloc=near&output=embed"></iframe><br /><small><a href="https://maps.google.com/maps?f=q&source=embed&hl=en&geocode=&q=3904+Washington+Parkway,+Idaho+Falls,+Idaho&aq=0&oq=3904+washington+parkway+idah&sll=41.833733,-87.731964&sspn=0.929078,2.113495&ie=UTF8&hq=&hnear=3904+Washington+Pkwy,+Idaho+Falls,+Bonneville,+Idaho+83404&t=p&ll=43.466874,-111.993513&spn=0.015573,0.025406&z=14&iwloc=near"></a></small>
