adding upload image from url form.

still working on finishing actual view.
removed unused import
testing new model with imagekit
transpose added
testing image rotate
using imagekit to transpose images as needed.

added new thumnail format to database, which chaches via s3 storage.
this should be a good solution for now. slice in template removes unwanted extra in url
removed thumb_location function. it is not needed
removed previous create thumbnail code
removed bootstrap thumbnail class
removing more remnant code from previous thumbnail creation
quality change for large images
removed thumb url from remove image
added thumbnail tag back in
fixed delete image function.

added in a split, which drops all extra in the url after the ?, and slice off remainder added on. Works well.
added split and slice to use direct s3 file urls instead of building them fromt strings
removed redundant code from views and models.

unused model fields that were not needed removed. added a new check for if a file exists by appending user id on the filename
removing instance of old style string format.

also added context dict in some cases. general clean up
changed fullsize image load to query db for filename
corrected for loop to grab images

need to revist adding cloudfont urls to db
working on cloudfront url function
