I just following this tutorial https://jamersan.com/lets-get-started-theming-magento-2-part-1/ , in this tutorial I learn about how to make Magento Theme, but unfortunately I unable to show Theme Preview Image.
When my previous Themes is having it:
theme.xml (myshop/app/design/frontend/MyCompany/default/theme.xml)
The Image
Database Table
I am curious why the preview image does not show on my theme info page ?
Any help about it extremely appreciated
Theme Preview image loads from app/design/vendor/theme_directory/theme.xml file
<media>
<preview_image>media/preview.jpg</preview_image>
</media>
If this media tag and path to the image is not specified theme preview image will not be loaded. You can follow this link to learn about Magento 2 Themes and Theme creation https://devdocs.magento.com/guides/v2.3/frontend-dev-guide/themes/theme-overview.html
I was able to fix that issues by deleting "design/theme/theme_id" from core_config_data table, and by deleting theme record in theme table as well. After that, I just activated theme again and thus, there is an image preview.
