How do I handle images and thumbnails jedd

Category:Approaches::How do I handle images and thumbnails

Overview:

I process all images as they are introduced to the system - that is, generating thumbnails, medium-sized, and perhaps retaining the original (full-size) image.

I store files within the file system. I allow for performance optimisation by using sub-directories. Files are renamed to UUID to ensure compliance with every file system out there, consistent-length names, guaranteed(*) uniqueness, removal of potential FS or OS name exploits, reduces potential for users to guess an image's URL.
