Uses original image data to extract orientation exif to apply image
transformations before scaling and save. Manually done due to issues
with exif data loss during the existing Invervention image path.
For #1854
Adds apng sniffing when generating thumbnails with retained ratios to
serve the original image files, as we do for GIF images, to prevent
the image being resized to a static version.
Is more tricky than GIF since apng file mimes and extensions
are the same as png, we have to detect part of the file header
to sniff the type. Means we have to sniff at a later stage
than GIF since we have to load the image file data.
Made some changes to the image thubmnail caching while doing
this work to fit in with this handling.
Added test to cover.
For #3136.
Replaces the old suggestion of setting JS head 'window.uploadLimit'
variable. This new env option will be used by back-end validation and
front-end libs/logic too.
Limits already likely exist within prod environments at a PHP and
webserver level but this allows an app-level limit and centralises the
option on the BookStack side into the .env
Closes#3033
- Moved out extension check to ImageService as that seems more relevant.
- Updated models to use static-style references instead of facade to align with common modern usage within the app.
- Updated custom image_extension validation rule to use shared logic in image service.
- Files within the storage/ path could be accessed via path traversal
references in content, accessed upon HTML export.
- This addresses this via two layers:
- Scoped local flysystem filesystems down to the specific image &
file folders since flysystem has built-in checking against the
escaping of the root folder.
- Added path normalization before enforcement of uploads/{images,file}
prefix to prevent traversal at a path level.

- Added testing to cover.
Related to PR #2320, and issue #1161
To ensure thhat the visibility is still set on local storage options
since the previous recent changes could cause problems where in
scenarios where the server user could not read images uploaded by the
php process user.
Closes#2758
The content of pages made non-viewable to a user via permissions, within a visible parent, could be seen via the plaintext export option. Before v0.30.6 this would have applied only to scenarios where all pages within the chapter were made non-visible. In v0.30.6 this would make all pages within the chapter visible.
As per #2414
