resize - Cached resized image provided even if it the original changed

[helmutkaufmann]

• Winter CMS Build: 1.1.3
• PHP Version: 8 (and 7.4)
• Database Engine: sqlite
• Plugins Installed:

Description:

When an image that has been resized using Winter's built-in resize Twig function, is replaced, the resize does not identify that and provides the resized version of the ORIGINAL image instead of the NEW image - probably as the modification date of the replaced image is not checked against the creation date of the resized image.

Note that https://github.com/toughdeveloper/oc-imageresizer-plugin provides a resize that actually checks for image file modification time and re-generates the images as needed. Perhaps this would be a solution.

Steps To Reproduce:

1. Place an image in the media directory and resize it, "image.jpg" | media | resize(200, 200)
2. Replace image.jpg with another image
3. Re-run "image.jpg" | media | resize(200, 200) --> the old image is served.

@helmutkaufmann can you give #178 a try and let me know your thoughts?

[helmutkaufmann]

Elegant solution, I have to admit. The PR works as I would have expected it. The only drawback I see is that this solution will result in a number of "orphaned resized" images but we will have those anyway when we remove images that have been resized.

@helmutkaufmann do you have any ideas for a console command that could automatically identify orphaned resized images and delete them?

[LukeTowers]

Only things that comes to my mind is just a command that purges all resized images to force a global reset.
