<div dir="ltr">Agreed. <div><br></div><div>The oddest thing to me is the behavior is specifically sensitive to being iframed. <div>The src= link used directly has attribution </div><blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div>"© <a target="_parent" href="http://www.openstreetmap.org">OpenStreetMap</a> and contributors, under an <a target="_parent" href="http://www.openstreetmap.org/copyright">open license</a>"</div></blockquote>
<div>but when used in iframe src= (exactly as shown as entire <body>)</div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>"Tiles courtesy of <a href="http://www.mapquest.com/" target="_blank">MapQuest</a>"</div>
</blockquote><div><br></div>If that's even correct on MapQuest (e.g. due to MapQuest ackn elsewhere on page), </div><div>it should only be true if iframe referer is *.Mapquest.com not some other site?</div><div><br></div>
<div>added thought -- If <a href="http://osm.org">osm.org</a> is serving tiles *rendered* by MQ perhaps *BOTH* are in order ! )</div></div>
