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.
Notes to self:
improving performance (substr(filename,0,2)) / filename
exif data retention (ideally relocated / replicated to thumb)
thumb, original, main - directories higher, to allow some splitting (show reference code)
