Researching how to create links within an image, I have found out about using image maps and also about image slicing in Photoshop.
An image map or use map is when you take parts of an image and create a link. You can specify exactly what part of an image will be a link by using the coordinates that relate to the image and in doing so create 'hotspots'. So you could have a map of the world on your website and then have each different country as a hyperlink. You would select Australia for instance and by using the coordinates of where Australia is in the image you could then create a link to an Australian website.
Using an image map is an easy way to link different parts of an image without having to divide the image into separate files. There is a very informative and easy to understand tutorial on You Tube that explains exactly how to create image maps. I found this video very helpful and also informed me of a great free resource for creating image maps online. The tutorial uses an online image map editor at
maschek.
You can view the video tutorial here.
Adobe Dreamweaver makes it easy to create image maps and there is useful information on how to do this
here.
Another way to create links within an image is to use image slicing in Photoshop. This might be particularly helpful in creating a banner on a website. Photoshop has a 'slice tool' (as shown left) that allows you to divide an image into smaller sections and it does this by creating straight edged sections like a table.
Here is an example of using the slice tool to create smaller sections within an image.
Notice that when you select an area with the slice tool, Photoshop automatically creates more slices to complete the image. The slice that you originally created is highlighted. You can manually move and resize the slices.
Slicing is an ideal way to optimize your image. You can make adjustments to the image such as making it a gif and/or changing the amount of colours used in the image and make your file sizes much smaller, therefore making loading time much faster.
