Imaginarium

A simple golang image storage engine. Used to create and store different sizes/thumbnails of user uploaded images.

Description

Imaginarium enables you to create copies (or thumbnails) of your images and stores them along with the original image on your filesystem. The image and its copies are stored in a file structure based on the MD5 checksum of the original image. The first character of the checksum used as the lvl 1 directory name.

Imaginarium supports png, jpg formats and also images encoded with base64. The decoder for any given image is chosen by the image's mimetype.
