On my system at least 'c:\windows\coffee bean.bmp' is an 8-bit
bitmap.
Using a 24-bit version has a slightly different effect, rather than
hiding the whole image the color appears to be turned on/off.
BTW Using your example code the image is visible when the button is
labelled "On". Isn't that sensitivity = 1?
