Capture URL Link click event in ProcessFormRequest

Question

Hi All,
I have requirement to capture the event and do some validation/dialog page whenever a URL Link is clicked on my Page.
I can handle the button click event in ProcessFormRequest, if I use a Button and sets its destination URI to a URL
However, if its a standard hyperlink or Image and Destination URI is set. The event is not being captured in ProcessFormRequest.
Is there any other alternative, apart from changing the Image to Button. Thats the restriction. Its has to be Image.
Or how to capture that event, when the URL is clicked.

Hi
Many thanks for the update.
The page I am working on is the standard Oracle Page ( Receiving Home Page in iProcurement). This page has table of Requisitions which can be Received.
Express Receive image is present corresponding to each Requisition in the tablelayout.
Once the express receive is clicked ( Destination URI property is set to OAFunc= Final Review Page Parameter= Req Header ID), the Review page is displayed with Submit button.
So as to change the ActionType of the Express Receive Image, I need to then customize the page and also extend the standard Controller code.
Instead just extending the COntroller to capture the URL click event
I guess, the URL click event cannot be captured in Controller. Hence the Property has to be changed and handled by code.
What i am worryin for this solution is that, whether the specific Requisition Header ID which is passed on the URL link, can be passed similiarly while writing the code for the Action Type of the Express Image. Or the code would though take to Review Page but miss out the specific Req Header ID against which it was clicked.
Pls advise
Thanks
