If you have physics bodies related with this images then collision event will be raised. (set isSensor=true, to allow overlaping) If not, then you can check it like this (but you have to check it in enterFrame event

img1:setReferencePoint(display.centerReferencePoint) img2:setReferencePoint(display.centerReferencePoint) -- TIP: logic fromula returns true or false for not rotated rectangular objects, -- if you wanna have rotation its require just a little bit more math ;) print ("overlaping: " .. tostring( math.abs(img1.x - img1.x) \< (img1.width + img2.width)/2 and math.abs(img1.y - img2.y)
