Need a tool / photoshop plugin to draw screen object dimensions

Hi,
I think most of the designers would have faced this situation of documenting the design and explaining the alignment, formatting and layout of the screen for documentation/testing(UI Validation)/HTMLization purposes.

What I’m looking out for is if there’s a tool which does this once the final prototype is ready? Even a photoshop plugin would do?

I’m currently doing the hard way by drawing the arrows and markers & adding the width/height… and i’m sure there must be an easy way out…please let me know.

Thanks,
Amy

my research led me to this link which shows that the feature is available in CorelDraw.

I thought Photoshop gurus in this forum would have a similar or better alternative…no replies still???

Wow! 128 views but no solution for this problem…amazing! Adobe has not thought about this most crucial requirement of designers.
