Hi Parth
A very good reference is
http://www.w3schools.com/wap/ for writing a WML file. Plz go through this. Make a *.wml file. Put this file and all the image files *.jpg etc.into a place where it can be accessed via an HTTP server. The scheme is such that:
1.From the target phone, open the Web browser. Hit the URL pointing to the *.wml. Click on the �Download� link to download the app to your phone.
2.The phone may ask some questions about whether you want to download the images, etc. Say yes to all.
Example: (Simple one)
<wml>
<card id='download' title=�MyApp�>
<p>Download buddypix:</p>
<p><a href='MyApp.jpg'>Download</a></p>
</card>
</wml>
Hpoe this might help u. let me know the result.
