I found this feature pretty interesting since it would allow site owners to save a lot of disk space.
Unfortunately this won’t implement properly into discourse, first because no icon appears in the text area toolbar for the “Upload images” button (see the little greyed area at the middle)
Second, this will just implement the image as a small link, in a different way than the default image upload feature built in Discourse.
A theme component should suffice for the upload component, but by default Discourse will download remote images to ensure they aren’t deleted.
Make sure to add imgbb to disabled image download domains after checking their policy about when images are deleted if you implement this upload widget.
Supongo que el desarrollo de un plugin así costaría entre 500 y 1000 dólares, lo que equivale a bastantes años de Digital Ocean Spaces (o cualquiera de los otros en Configurar un proveedor de almacenamiento de objetos compatible con S3 para subidas). De hecho, probablemente sería más barato usar Spaces que pagar por mantener el plugin descrito si existiera.
