How to enlarge an image in Vf page

I have developed inline vf page in which there are group of images. 
How to enlarge a particular image on mouse events (Like onclick, mouseover etc.) ??

Hi Maxi,

Visual force supports HTML and JavaScript and if you want to Zoom out and Zoom in You can use Javascipt or CSS to achieve this functionality. 
Please try the below code

<apex:page >
img:hover {
height: 200px;
} </style>
<apex:image id="theImage" value="https://s3.amazonaws.com/{!bucketToList}/{!obj.key}? AWSAccessKeyId=AKIAJGN4J4RSRNW26IEA&amp" width="220" height="55"/>

Please let me know if this helps

Best Regards

One question from my end here.
Shall we implement this functionality using action functions?
