I am working with a custom post type ('istuff') and custom taxonomy ('generation').
I want to display a page which lists all the istuff, grouped by generation (i.e. iPhone 4S, iPod Touch 4g, iPad 2 etc in one group - iPhone 4, iPod Touch 3g, iPad etc in second group and so on). Each generation is preceded by a thumbnail image (perhaps taken from the first istuff in generation?) and a description (pulled from the description in custom taxonomy admin menu), however each istuff does not have a thumbnail. To make things even more difficult (sorry), I want the thumbnail to be a custom size ('Generation Title').
I have tried using the plugin Category Images II by Simon Wheatley to get the custom taxonomy to have a thumbnail attached to it, however this does not allow me to display this in a custom taxonomy archive page, nor does it allow me to define the custom thumbnail size.
I know there is a plugin to create a "Category of Category" page, although I'm not sure that is the best method of attack.
Any ideas? Am I approaching this completely the wrong way?
