[RESOLVED] Get new picture?

[Slyke]

This can be done with JavaScript or AJAX (It just has to work with all browsers).

My goal is to use a PHP script to return a picture's path, and then load the picture. The PHP part of the script is no biggy.

echo getPicturePath(); 

Which will return 348344.jpg for example.

The bit that I can't workout how to do is to do this every second or so, and then actually load this picture onto the webpage.

Here's a thoery I've come up with, using JavaScript:

<script>
var objPicure;
var latestPicture="";

init()
{
  objPicure=document.getElementById("thePicture");
}

loadNewPicture(fileName)
{
  ??? //Loads the picture from the fileName URL and puts it into objPicure
}

updatePictureFile()
{
  latestPicture=???; //Get the filename from the PHP script.
}
</script>

<img src="loading.jpg" id="thePicture" /> 

I'm familiar with JavaScript timers and would implement them too, just want to keep the theory simple.

Any tips ?
