i am preparing graphs(MatPlotLib) related files using external methods.,
when i test them on zope they display very well there.

But when i call these external methods using tal as:

<Img tal:attributes="src python: context.IterationBar(context) "/>
where IterationBar is my external method that displays a BarChart.

Or using

 <img src="/Agile/image.gif"
   tal:attributes="src context.IteartionBar(context)"/>

1) the thing you're calling must return an *URL*
  not the image data itself...think about how the <img>
  in HTML works

2) The script called through the given url must return the image
  data _and_ it must set the proper http headers content-type,
  and content-length

 If your site is only for FireFox or evolved browser you can use inline
rendering:
<img  width="81" height="85"
 src="data:image/gif;base64,R0lGODlhUAAPAKIAAAsLav///88PD9WqsYmApmZmZtZfY
