Description

Imstor 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 (zero-prefixed, decimal) CRC 64 checksum of the original image. The last 2 characters of the checksum are used as the lvl 1 directory name.

Imstor supports any image format you can decode to go's own image.Image and then back to your preferred format. The decoder for any given image is chosen by the image's mimetype.

Example folder structure

Folder name and contents, given the checksum 08446744073709551615 and sizes named "small" and "large":

/configured/root/path/15/08446744073709551615/original.jpg
