Thanks for your reply Kovid.
But it did not work with dataURL as well.
I used following img tag
<img src='data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOy DZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7////wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQ AosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIg UhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB 0UjIQA7'/>
Please let me know if I am missing anything.
