image size and depth

[Yves COPPE]

Hi list,

I have a file which is a jpg file
This img is taken with a digital camera

I'd like a script which would change the size and the dpi of this img. 
The idea is to dim the size and set the dpi to "100" or "72"

For now I use graphicConverter but I'm asking if it would be possible 
to make it from within Revolution ?

My script begins with

answer file "Where is the image ?"
if it is empty then exit to top
put it into filepathToImg
...
...

Thank you very much.

Greetings.
