Creating sidebar images:
There are loads of programs available to create simple sidebar buttons! I recommend either Picmonkey or Picasa to do the job. Both come with really great tools that make it easy to create dynamic images and both are FREE! You can use their library of fonts to create a simple button or use images you've taken and edited to create buttons.
Once you have your images ready you can begin coding them into your layout.
Step 1: Setting up the widget for your buttons.
To create the widget for your clickable buttons select Layout from the Blogger Dashboard then select Add a Gadget.
Step 2: Adding the image URL code
Select the HTML/Javascript option > Then add the following code to your widget and change the RED portion to your image URL:
<img src=”http://yourimage.jpg”>
Step 3: Linking the image as a clickable button
Highlight the code and select the link option in the widget. Type in the appropriate link URL (this is where you want the button to link to) and select 'OK' then save your widget.
Step 4:
That's it! Repeat for as many buttons as you would like!
