Re: Displaying images on buttons in Forms 5.0

Sounds to me like it may work out better to "draw" the image of a button with your large format picture on it. Add an image item (the little easel on the toolbar). Then, attach to that a WHEN-IMAGE-PRESSED trigger to perform the same functions that pushing a regular button would have.

There are some disadvantages to this method. The primary one is that the image has to be read from disk every time that screen is called up (if the picture was stored in the databse, then this wouldn't be true). Every time disk access is done, there's always a possibility for slow reading. What's more when you have a lot of the same image repeated on a page (for example, to show that a field has a List of Values associated with it) then disk i/o must be queued since multiple requests for the same file is done. An obvious work around is to use different names for the same image.
