The TW core wikify() parser already defines a regular expression for
each kind of 'formatter' that it recognizes, including one for the
"image" syntax:
config.formatters[config.formatters.findByField
("name","image")].lookaheadRegExp;
which has a default definition of:
/\[([<]?)(>?)[Ii][Mm][Gg]\[(?:([^\|\]]+)\|)?([^\[\]\|]+)\](?:\[([^\]]*)
\])?\]/mg
To view an example of some plugin code that modifies the image
formatter's regexp (and the associated handler), see:
http://www.TiddlyTools.com/#ImageSizePlugin
(The plugin adds support for an optional "[img(x,y)[...]]" syntax that
allows the rendered image to be automatically scaled to a specified
size)
