jquery.tipTip displays tooltip text randomly

I am using jquery.tipTip to display text on image’s mouseover but it randomly activates and displays the text when there is no mouseover on the image.

$('.tooltip').tipTip({maxWidth: 'auto', edgeOffset: 5, defaultPosition: 'top', keepAlive: false, activation: "hover"}); [![enter image description here][1]][1]
