Do you want to modify action's properties (RowCount/ColCount)?

It is possible.

Process OnExecute of this action.

Inside OnExecute, call the following:

<your initialization code here>

actioninserttable.OnExecute := nil;

try

  actioninserttable.Execute;

finally

  actioninserttable.OnExecute := actioninserttableExecute;

end;

This technique is useful if you want to call your code before and/or after

the standart action execution.

You can display TOpenPictureDialog even without action :)

What do you want to do instead of inserting image? May be I can add this

functionality to the action
