Hello. I'm using JS/DOM to create a map in a <div>, named map, like this: [code=javascript]var tile = document.createElement("IMG"); tile.src = "tiles/" + node.getAttribute("type"); tile.setAttribute("width", "32"); tile.setAttribute("height", "32"); tile.className = "brick"; map.appendChild(tile); [/code] It works, but the image breaks on a <br/> (screenshot: [url]http://i28.tinypic.com/6ynu3o.png[/url]) the image is a 32x32 tile …
