Appear bigger when the user hovers over it with the mouse. I’m not really sure what the best approach is. Sorry if this is not php related but if you can point me in the right direction I would appreicate it.
Following from Rubbles comment, Id probably choose a misture of both
Write two images in your HTML,one thumsized and the following one the full size image. give the full size image a default CSS of “display:none;” so it doesnt display then on the mouse over of the thumb change the CSS of the display operator via javascript.
Thats only a very uncomplicated method, there are other things to consider such as making the “popup” image not break your normal page layout etc.
