Key word driven properties

[rajeshdizzy]

In keywordriven properties ,the property capturebitmap.
i did this property by using the google and created a bmp image externally and i wrote like this

Code:

browser("google).page("google").capturebitmap "c:\mypictures\raj.bmp",true

So my doubt is to check the image y we have to call the image from outside.and still i dont understand about the overrideexisting......pls any one explain with an example..


Thankz in advance
