I found a very useful tip from an online parenting blog. Click here to gain access to the blog. It is about protecting the pictures in your blog. As I found it very useful for me, i thought I should share it here too.
However, while trying them out by following the instruction listed in the blog, I realised that some of the directions had changed.
This is what I found out :
To disable right click function, follow Step 1 as listed in the blog.
To disable left click function, follow Step 2 as listed in the blog.
To disable the Image Toolbar, follow Step 3 as listed in the blog.
My advise is to always do a preview of your blog before saving the changes.
