It seems like the only way to add image as a Project Cover Image is to upload the image to the Media library and add it from there.
We have images hosted outside of the wordpress and would like to just add a link to an external image as a Project Cover Image.
Is there a way to do that?
I hope you are well today and thank you for your question.
To achieve this, you have to develop custom code in the child theme of Jevelin theme.
Developing custom code for custom functionality is beyond the scope of support that we provide here. Please see https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
