How to use?

http://{server}/images/{storage}/{size}/{path_to_file}

server - imgwizard server addr
mark - mark for url (can be used for nginx proxying)

How to install?

Installing libvips

VIPS is a free image processing system. Compared to similar libraries, VIPS is fast and does not need much memory, see the Speed and Memory Use page. As well as JPEG, TIFF, PNG and WebP images, it also supports scientific formats like FITS, OpenEXR, Matlab, Analyze, PFM, Radiance, OpenSlide and DICOM (via libMagick). (© vips wiki)
