This page is designed to show you how some webmasters have tried to trick search engine spiders. This is what I call small images, or 1 x 1 image links (dimensions of the image). Small image links can be placed on your page so that they take up only 1 pixel of your screen. This is very very very small. It is very hard to click on if you were trying to and there is an example below:

|
| 41 x 38 pixels | 36 x 33 pixels | 31 x 28 pixels | 26 x 23 pixels | 21 x 18 pixels | 16 x 11 pixels | 11 x 8 pixels | 8 x 3 pixels | 1 x 1 pixel |
As you can see from the above table, the picture that is 1 x 1 you can't see. You can basically hide links this way. By making the picture so small you can't see it. Look at the below table of links that have been done in the same sort of way that the above table is constructed.

As you can see, each image links to my main page. Even the 1 x 1 image. You can get this link to work by click somewhere in the cell of the table then hit the "TAB" button. You will notice a tiny dot appear. Hit the "Enter" button to follow the link.
With the above examples there is no border on the image links. This is easily set by the image attribute "border". So the link coding for the above image of 1 x 1 pixel looks like this:
<a href="index.html"><img src="images/i.gif" width="1" height="1" border="0"></a>
Not only can I hide a link within this nearly invisible picture, but I can also add ALT text to the img tag to get even more keywords in there like this:
<a href="index.html"><img src="images/i.gif" width="1" height="1" border="0" alt="spam, spam, spam, spam, spam, spam, spam, spam, ..."></a>
Try not to use this sort of technique when creating your pages. It is quite easy for search engine spiders to see this. It doesn't take much to look at the width and height variables for an image.
