I recently found a Canon P&S on the road and having been unable to locate the owner I realized the value of customizing the start up image on my own cameras to show, for example, my phone number and "Reward!".
So I managed to record and set a suitable image on my S5 and A95 that does show up on startup but only for a brief moment - too fast to really see what it is.
I can't find any way of setting the start up image to show for a longer time. Have I missed something in the manuals, or is is not possible?
