Export picture in to a webviewer website

[ibobo]

Hello, 

does anyone know how can I upload a picture from my desk or any other folder in to a website with button "browse"  using a script ? 

 for exemple - first  action select the file in the folder according to his name stored in a field 

then - click on "choose" 

the rest I can do but I can't find any way to do it >< 

here is a screenshot 

 

Thanks you
