Two solutions.

  1. Build a handler page. That takes an ImageID/RowID as GET parameter and returns data with mimetype image/jpeg or image/png.

  2. Use DATA uri scheme as explained on wikipedia.

    <img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABGdBTUEAALGP C/xhBQAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9YGARc5KB0XV+IA AAAddEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIFRoZSBHSU1Q72QlbgAAAF1J REFUGNO9zL0NglAAxPEfdLTs4BZM4DIO4C7OwQg2JoQ9LE1exdlYvBBeZ7jq ch9//q1uH4TLzw4d6+ErXMMcXuHWxId3KOETnnXXV6MJpcq2MLaI97CER3N0 vr4MkhoXe0rZigAAAABJRU5ErkJggg==" alt="Red dot" />
