Can I do this?
$("#myImage"+1).attr("src", "path/to/newImage.jpg");
Because the image is like an array so the id for the img tag is myImage1
<img src="path/to/oldImage.jpg" id="myImage1">
Yes, you could iterate round image elements like this:
for (var i=0;i<=5;i++)
{
$("myImage" + i).attr("src", "path/to/newImage.jpg"); ?
}
