When you click part of a website image and your browser jumps to a different Web page, an image map is probably responsible for that action. Site designers can write HTML code that creates clickable hot spots on any picture. Constructing image maps by hand is time consuming because you must identify the exact coordinates of each hot spot. With the Slice tool in Photoshop, you draw hot spots on an image to generate the HTML code you need automatically.
Create Image Map
Launch Photoshop and open an image you want to convert into an image map. Click and hold the "Crop" tool to display a menu containing other tools. Click the "Slice" tool to select it.

Click a point inside the image and drag the Slice tool to draw a bounding box around the part of the image you want to make clickable. Photoshop draws additional "auto slices" around other parts of the image. These auto slices ensure that all parts of an image are included in a slice.
Right-click inside the slice you created and select "Edit Slice Options" to open the Slice Options window. Type the URL you want to associate with the slice. You can also replace the default name that Photoshop gave the slice by typing a new one in the "Name" text box.
Click "OK" to close the Slice Options window and return to the image. Click another point inside the image and drag the Slice tool to create additional slices as needed.
Adjust Image Map Slices
Select the "Slice Select Tool" from the toolbar and click inside a slice you want to move.
Hold down the left mouse button and drag the slice to a new location.
Hold the mouse cursor over one of the slice's edges and a line with arrows on each end appears. Click that line, hold down the left mouse button and drag the mouse if you need to make the slice bigger or smaller.
Save Image Map
Click "File" followed by "Save for Web" to open the Save for Web window.
Click "Preset" and select one of the file type options that appear. Choices include GIF 128 Dithered, JPEG High and PNG-24.
Click "Save" to open a window that displays your hard drive's files and folders. Browse to the folder where you want to save the image map files and type a name for the image map in the File Name text box.
Click the "Format" drop-down menu and select "HTML and Images." Click "Save" to save all files to the folder you specified.
