store.basic.php is used when there are no promo items, so it is still relevant - it's a confusing and rather useless template system.
I have 2 options for category images:
- either, add an extra field and include that in the template,
- or, provide for WYSIWYG which also resolves the image upload issue if you use SPAW.
- At this stage, WYSIWYG is my preference.
btw, Pitcher's SPAW release for 9.1.1 also works just fine in 9.2.1 - I just need to find the minor bugfix I made to a javascript.
The loosely called, and grossly inadequate, Storez "template" system is in the process of being converted to a real template system, initially in the store and product display areas. That will eliminate the confusing double template issue and restore full layout control to the theme.
