How do you create an image with php?

[Polarbear4646]

How can I create an image like the horizontal bars in a poll? If you give me code can you explain it, or without code tell me how I should go about it?

It can be normal JPEG image and change the width:


<img src="/bar.png" width="98" /><br />
<img src="/bar.png" width="63" /><br />
<img src="/bar.png" width="38" /><br />
