Javascript Image Resize

Question

Does anyone know how to resize images proportionally using JavaScript?

I have tried to modify the DOM by adding attributes height and width

Answer 1

Use JQuery

var scale=0.5;

minWidth=50;
minHeight=100;

if($("#id img").width()*scale>minWidth && $("#id img").height()*scale >minHeight)
{
    $("#id img").width($("#id img").width()*scale);
    $("#id img").height($("#id img").height()*scale);
}
