Currently I'm using version 1.3.6 of Arras Theme, a great theme with great use of thumbnails on the front page. But it was created pre WP 2.9 so the thumbnail function of WordPress isn't used but a custom field 'thumb'. Version 1.4+ of this theme does use the thumbnail function but I don't like the layout of 1.4 so I'll stick with 1.3.6 for the time being.
But I sure would like to use the thumbnail function of WP itself. I've asked the creator of the theme if it could be implemented in 1.3.6 easily but that isn't the case. So I'm here on WP forum itself to ask the following question:
Is it possible to tweak the thumbnail function of WordPress so it automatically creates a 'thumb' custom field when choosing a thumbnail while creating a post?
