Problem:
If you set English as your primary language and Bulgarian as your second, then completely remove Bulgarian, you are concerned that this will also delete associated images, leaving English products without pictures.
Solution:
Changing your site's default language to English will not affect the default language of your products, and images will still appear if the products are created in English. However, since Bulgarian was the default language for many posts, products, and other custom post types, you should take the following steps to properly remove Bulgarian content without affecting English content:
1. Temporarily reactivate the Bulgarian language.
2. Navigate to Posts, switch to Bulgarian, select the posts, and delete them.
3. Clear the trash.
4. Repeat the process for other post types like Products, Pages, and Templates.

Additionally, ensure to back up your site before making any changes. We also canceled automatic translation jobs that might have been stuck due to content originally being in Bulgarian.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.
