The easiest way is probably to use TaskMaster.  If you set the tmMultiClick
bit in wmTaskMask, TaskMaster will time multiple clicks for you using the
multi-click time in the Control Panel.  The number of clicks will be
returned in the wmClickCount field.  (Note that you must be using the long
form of the task record, as documented in Toolbox Ref. Vol. 3, in order to
use this feature.)

     { The following bits seem to be missing from Windows.p }
     CONST tmContentControls = $10000;
           tmControlKey = $20000;
           tmControlMenu = $40000;
           tmMultiClick = $80000;
           tmIdleEvents = $100000;

     VAR myTaskRecord: WmTaskRec;
         myEventMask, myTaskCode: Integer;

     { ... }

     myTaskRecord.wmTaskMask := tmMultiClick + { whatever ... };

     { ... }

     myTaskCode := TaskMaster(myEventMask, myTaskRecord);
     IF myTaskRecord.wmClickCount > 1 THEN
          { multiple click occurred }
     ELSE
          { single click occurred }

This is fully documented in Toolbox Ref. Vol. 3.

The first method that occurs to me is to create a picture or an icon
containing your image, and save it in your program's resource fork.
Call LoadResource to bring it into memory when your program starts,
and then use DrawPicture or DrawIcon to display it.
