Is it possible to start an application such as 'photoshop' by clicking on an element on a  local web page??
How would I go about doing this??
Thanks in advance..

The general answer is, "no".  But why would you want/need to?  If you have Photoshop installed on your machine, why would you want to start it from a web page rather than to simply open it on your desktop?  If this will be aimed at visitors, the same question applies.
It
may
be possible in some inherently insecure browser such as Internet Explorer with Active-X.  I wouldn't know about that, nor would I implement such a thing if I did know how it was done.
cheers,
gary

Gary is right. The amount of time working all those functions in via (I assume JavaScript), it wouldn't even be worth it. As Gary said, what is this for? Photoshop on the desktop would probably be a bit more friendly then one on a webpage.

Photoshop was just a example. The actual applications are simple keyboard entry and typing tutors aimed at people with limited computer and literary skills. It pages would include links to popular job sites here. I am just trying to come up with a simple system that people would not have to mother hen them all the time.
Could I start application in the windows system using a Java applet or Java script . It been a long time does Java run time development  allow operating system calls.

Well since this is the HTML department of this forum, I think only a few would be able to answer that. Best you move on over there.

From the Applet Security FAQ:
Can an applet start another program on the client?
No, applets loaded over the net are not allowed to start programs on the client. That is, an applet that you visit can't start some rogue process on your PC. In UNIX terminology, applets are not allowed to exec or fork processes. In particular, this means that applets can't invoke some program to list the contents of your file system, and it means that applets can't invoke System.exit() in an attempt to kill your web browser. Applets are also not allowed to manipulate threads outside the applet's own thread group.
As a general statement what you want to do is not possible in a cross-platform (O/S and browser) way.  It is a security risk if the browser is allowed to start any program.  As kk5st indicated you might be able to write a Windows/I.E. specific ActiveX control but even then the end user might be required to active the ActiveX control or allow it to run.
