Question

I have control in a page that gets html from text file and renders that html in webpage.
Right now it has to add image somewhere and reference that image src.

I was wondering if we can render image along with other html code, is it possible?

Answer 1

Yes, it is. You need a Data URI scheme:

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

The same can be done in CSS:

ul.checklist > li.complete { margin-left: 20px; background:
  url('data:image/png;base64,
iVBORw0KGgoAAAANSUhEUgAAABAAAAAQAQMAAAAlPW0iAAA
ABlBMVEUAAAD///+l2Z/dAAAAM0lEQVR4nGP4/5/h/1+G/5
