I was pleasantly surprised to see Gantry comes pre-loaded with
belated png
, which is great. However I couldn't find any Gantry specific documentation about it.
In the end I got it to work quite easily by entering styles in line 71 in templates > rt_gantry_j15 > gantry.config.php
Hope that helps someone else who's client has insisted their site still works in IE6 (and needs pngs )
