This plugin provides two new template tags to replace plain text with styled images.
When you unpack this plugin, you'll find two subdirectories of the ttftitles directory. These are the fonts and cache directory. You must have a writable cache directory. If you chose to keep it inside ttftitles, then make sure you 'chmod 777' the cache directory. If you move it, tell ttftitles the new location in the 'Presentation/TTF Titles/Cache' admin page.
The fonts directory only has to be writable if you want to be able to upload fonts through the admin page. If you want to, then feel free to 'chmod 777' that directory as well. As with the cache directory, you can move it elsewhere if you really feel the need. Just update the location in 'Presentation/TTF Titles/Fonts'.
Note to users of Windows and other legacy operating systems: 'chmod 777' is Unix-speak for making something world-writable. Please substitute whatever your OS requires instead.
