Bluimp gallery

i thought bluimp gallery was gonna create thumbnails for me on the fly,
but
actually the docs say to build links to files in images and
images/thumbnails so was I mistaken, how are thumbnails gonna get
created
for pictures uploaded by my site’s users?

If you are using Paperclip or CarrierWave to do the uploading, both of
them have a set of options for creating multiple versions of an uploaded
file while it is being saved on the server. Assuming the upload is
anything that the Image Magick library can open (which is quite a lot of
formats) you are all set. Both of those “attachment” toolkits have
extensive documentation explaining how to set this up and configure it.

There’s another library called Dragonfly (and a very new one called
Refile) that share another approach – they “lazy-resize” images on the
fly, and then cache them for re-use, so you only upload one size, then
any time you want a different size, you pass a specially-crafted URL to
the image rout, and the resized version is generated (or fetched from
cache) on the fly.
