## 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
/configured/root/path/15/08446744073709551615/small.jpg
/configured/root/path/15/08446744073709551615/large.jpg
```
