Add classes to your html tags and the innerHTML is then automatically parsed into images with specified size, font, and color.
Upload the font file to the fonts directory. ie, wp-content/plugins/fresh_text/fonts/my_font.ttf
Just change line 5 of replacement.php from
var class_to_replace = "freshout";
to var class_to_replace = "some_other_name";
That's not what your mom said last night.
