The image Tag
The image tag generates an <input type="image"> element. The image tag must be nested inside a form tag. The image tag is similar to the submit tag, but instead of a submit button, you have an image that you can click to submit a form. For example, the displayAddProductForm.jsp page in app03d has the following image tag.
<html:image src="images/submitImage.gif"/>
This is rendered as
<input type="image" name="" src="images/submitImage.gif">
You can click this image to submit the form.
The list of the image tag’s attributes is given in Table 3.17.
