Use New Image Size For Subcategories Thumbs In Ps 1.6.4.1 Default Theme?

[iggywebprom]

I need some help with new image size for subcategories thumbnail. For now I have it working, but thumbnail is displayed only when a subcategory has category_default image uploaded. Then after I add a thumbnail to such category it is shown. But if I delete category_default image it is also deleting subcategory thumb. Any way to avoid such behavior?

 

What I did:

• Added new image size for categories and disables medium_default for them
• Added CategoryController.php into /override/front with included new size
• Added AdminCategoriesController.php into /override/admin with new size name (replaced medium to new name)
• Modified category.tpl with new image size name and image sizes
• Modified CSS to show images correctly.

As I said before it is working well.

But looks like category_default and category thumbnail are linked between them and we must unlink them somehow.

Any ideas from the community?
