Edit footer.tpl file located in your current template folder (/templates/YourTemplate/ for phpLD 3.0.5+ and /templates/ for all previous versions) and add following code to desired place:

              
{* Display TagClouds *}
{$tagclouds}
              
            
Clean compiled template files
Finally the last step, remove all files located in your /temp/templates/.

Customization
The Tag Clouds output can be fully customized by adding CSS properties.

Customize style
You can easily change properties for fonts, margins, colors or anything else, by adding CSS properties.

The Tag Clouds box is a DIV with class name tagclouds. Style all the rest of the child tags using the parent tagclouds class.

A simple example is:

              
.tagclouds { margin:0 auto; padding:20px; width:70%; border:1px dotted #9EC2F3; }
.tagclouds h3 { font-size:150%; }
.tagclouds .cloud-word { /* add you general rules for ALL tags */ }
              
            
You can also add custom colors and text styling for different tags if you have defined a number for CSS classes:

              
.cloud-style-1 { color:#0000ff; /*blue*/ }
.cloud-style-2 { color:#000; /*black*/ }
.cloud-style-3 { color:#e98800;/*orange*/ }
.cloud-style-4 { color:#0fb400;/*green*/ }
.cloud-style-5 { color:#ff0000;/*red*/ }
