            # when I write new blog posts I usually have a temporary folder called new_post on my desktop
# that I place images I want to upload to amazon s3 (which is distributed as CF) and then
# get the appropriate URLs to put the images in my blog post
 
# I usually save files as some_slug.png and some_slug_1200.png 
# with the latter being a larger version (1200px wide) of the first. 
# a typical upload will include 20 files. 2 versions of some (sm and lg), and some orphans
# so this compares filenames and if it detects a larger version of a file,
# it links the the smaller image to the larger image (i use fancyzoom on my site)
# if not, it just links to the image
