Alternate Text Attribute Splitter
Splits your alt and title tags into separate attributes
Description
This utility is useful in combination with Markdown where it’s not possible to set classes and other attributes on your links and images. Basically, it parses your alt attributes on all elements and looks for common string patterns so that this:
class:some-class;; alt:Some great text;; align:left
Becomes:
class="some-class" alt="Some great text" align="left"
Just separate your attributes using “;;” (the space is important). If you still want to include an alternate text attribute (alt="…") or a title (title="…"), just include them in the list (as in the example above).
