The new static 25000u file size for images is a good reduction for images that take photos of a large scene, but for images that depict a single thing such as a person or object, the file sizes used to be sometimes under 4000u, causing a 6x increase in their file size due to this update.
I suggest that with this new static sizing system, making single-object photos only 4000u or 5000u would be in line with past file sizes while still compressing larger images somewhat to make both types of image worth storing in a file system.
