I put "<p><img src="http://postimg.org/image/sjzrkipbd/"></p>" in the source code, but then when I posted it, the image didn't show up, and then I clicked edit and went into the source code and it was changed to
"<p><img src="http://postimg.org/image/sjzrkipbd/" /></p>" and I can't find any way to change it without it changing back.
