Question : How to run app on local machine and display results in web page

I have a VB6 app creates a jpg file.  I have a web page where I want to initiate this app and display the jpg file it creates.  Problem is, we use Firefox and Chrome where ActiveX is not supported.  Does anyone know of a way to trigger the local app and retrieve the jpg file created to a php web page?  Indirect methods are acceptable, but I'm hoping to keep it simple enough for our average user.  My app interfaces an ePad signature-capturing device on the local PC, so it needs to be run locally, not on the server.

Answer : How to run app on local machine and display results in web page

The only solution that I can think of is to apply the principle of other locally installed programs that are started by clicking a link on a web page (e.g. Skype, RealPlayer, etc.).
If web page contains a link in a form <a href="skype:SkypeID"> on a computer that has Skype installed it will start Skype (and make a call to SkypeID), on other computers an error will be generated:
--------------------------
The webpage cannot be displayed
Most likely cause:
Some content or files on this webpage require a program that you don't have installed.
--------------------------

I do not know how you associate a protocol to the program (e.g. link <a href="myprotocol:something"> starts your program) but I'm sure that you can find it on expert-exchange on some other forum.
