If you want text to pop up when you run the mouse over the graphic, then you need to add the alt
tag.
<img src="images/apple.gif" alt="This is my apple">
Specify Height and Width
If you want to adjust the height and width of the image then you need to use the height and width tags:
<img src="images/apple.gif" alt="This is my apple" height="100" width="150">
To add a border to your image need the "border" attribute. It's very simple:
<img src="images/apple.gif" border="5"> The 5 represents the thickness of the border. The higher the number, the thicker the border. The number 0 is equivalent to no border. Or you could just leave the border attribute out if you do not want one.
