I've tried editing the default image size for thumbnails on wordpress through settings > media, for both medium and small images, however it doesn't seem to be making a difference.
I've also regenerated the thumbnails multiple times, deleted and reuploaded them, but still they won't seem to budge from 300.
When I view the source, the thumbnails are parsing as:
img width="300" height="300" src="
and totally ignoring the dimensions set via the admin cp.
When I change from my custom template to twentytwelve, the dimensions change from 300 to 288px.
Where are these dimensions being pulled from? It's starting to drive me nuts.
Thanks in advance.
