Update the text to imaeg and image to image graphs to work with the new model loader. Currently only supports 1.x models. Will update this soon to make it work with all models.
- `DiskImageStorage` and `DiskLatentsStorage` have now both been updated
to exclusively work with `Path` objects and not rely on the `os` lib to
handle pathing related functions.
- We now also validate the existence of the required image output
folders and latent output folders to ensure that the app does not break
in case the required folders get tampered with mid-session.
- Just overall general cleanup.
Tested it. Don't seem to be any thing breaking.
- remove `image_origin` from most places where we interact with images
- consolidate image file storage into a single `images/` dir
Images have an `image_origin` attribute but it is not actually used when retrieving images, nor will it ever be. It is still used when creating images and helps to differentiate between internally generated images and uploads.
It was included in eg API routes and image service methods as a holdover from the previous app implementation where images were not managed in a database. Now that we have images in a db, we can do away with this and simplify basically everything that touches images.
The one potentially controversial change is to no longer separate internal and external images on disk. If we retain this separation, we have to keep `image_origin` around in a number of spots and it getting image paths on disk painful.
So, I am have gotten rid of this organisation. Images are now all stored in `images`, regardless of their origin. As we improve the image management features, this change will hopefully become transparent.
