Using cloudinary or any other web services for image storage


I am trying to use cloudinary with the following theme

But I had difficulty setting it up. I was able to change my config, but I am unable to replace all my existing image links with cloudinary.

I don’t have preference in provider, would appreciate it if anyone could point me to a guide to walkthrough setting up image storage for custom themes.

I’m looking for an integration with an image storage provider, as I seem to encounter errors on digital oceans when my images are huge (2mb above), when it comes to publishing a post and viewing the image on the site. It crashes the website, where I would see the nginx page or 503 service unavailable. I’ve tried manually uploading to cloudinary, but I’m unable to replace gallery images with custom image url.
