This plugin allows the creation of tag clouds based on GIF images.
Each word in the taglist is converted to an image. The images may vary in size, orientation and color. The images are then positioned in a condense way, resulting in <a href="http://www.wordle.net" title="Wordle" rel="nofollow ugc">Wordle</a>-like tag-clouds.
To use the image-style tag-clouds set the format parameter of <code>wp_tag_cloud</code> to <code>image</code>. For convenience a shortcode is provided <code>[imagecloud]</code> that will insert the tag-cloud with the image format option set anywhere within a post or page. The imagecloud shortcode will accept all arguments that <code>wp_tag_cloud</code> accepts plus the few additional ones described below.
To control the image creation a few extra options are provided that may be provided with <a href="https://codex.wordpress.org/Template_Tags/wp_tag_cloud" title="Template Tags/wp_tag_cloud" rel="nofollow ugc"><code>wp_tag_cloud</code></a> or the <code>[imagecloud]</code> shortcode. These are:
<ol>
<li>fgcolor: The color of the texts in the images. Must be in the format “#AABBCC”.</li>
<li>fgcolor2: A second foreground color. When this is set, the tag text color will be a color between fgcolor and fgcolor2, depending on the tag count (occurance). Must be in the format “#AABBCC”.</li>
<li>bgcolor: The background color of the texts. Must be in the format “#AABBCC”.</li>
<li>transparent: set to true if you wish to make the image transparent. Do not forget to set the bgcolor also to prevent strange text-edge colors as the texts will be anti-aliased.</li>
<li>margin: set to the amount of pixels added around each tag.</li>
<li>font: set to the file location or url of the TrueType font (TTF) file to be used to create the tags.</li>
<li>percentup: percentage of words that is to be rotated 90 degrees.</li>
</ol>
