Often when designing websites static or dynamic, PHP or ASP.Net, Laravel or WordPress, you have to design in a way if user hovers an image it gets changed and an alternate image is displayed. This can be easily achieved via simple HTML events. Here is the trick:
<img src="FIRST IMAGE URL GOES HERE"
onmouseover="this.src='SECOND IMAGE URL GOES HERE'"
onmouseout="this.src='FIRST IMAGE URL GOES HERE - AGAIN'" />
It is simple as that.
