				|  Posted: Sun Oct 17, 2010 12:04 pm    Post subject: Looking for a HTML / CSS image trick |   |  
				| 
 |  
				| I'm coding something that acts as a web server as part of its functionality, and I'm using embedded base64 images to make my job easier. For example: <img src="data:image/gif;base64,R0lGODlhEAAQAHAAACH5BAEAANgALAAAAAAQABAAhwAAAAAAMwAAZgAAmQAAzAAA/wArAAArMwArZgArmQArzAAr/wBVAABVMwBV...... " />
 
 The problem is that in certain circumstances that image needs to be used in about 12,000 places in the document. In that case I end up with a page size exceeding 20MB, which is obviously unacceptable.
 
 I know I could place the embedded image in a single span element and duplicate it on the client side using JavaScript, but I'd much rather use CSS or HTML to do it since JS isn't always enabled.
 
 Any ideas?

				| I can't recant any CSS trickery, but if the problem is related to your difficulty handling multiple document requests then you could always host the image on a different server. |  |

				| Wow, this reminds me of an IE image html exploit. Like you are trying to override a buffer when calling an image to either ddos IE or install something without user interaction as the user running IE. _________________
