Flickr image puller.

/*
V1.3.1  // Updated the script to accommodate flickrs new API change. This now uses SSL.
V1.3    // I added the option for the user to specify the resolution the picture received should be. This uses
    Flikrs URL suffixes, so to determine what suffix you want, go here: https://www.flickr.com/services/api/misc.urls.html
    Then edit the size_suffix variable. As a note, the file type can be .jpg .png or .gif. It has to be the original format tho.
V1.2    // I really should test my updates before posting them here... It works now. Yes I tested it :P
V1.1    // Script no longer pops up with alerts boxes, and random, but not the same feature now works.
V1.0    // Posted, worked sorta, but forgot to remove alert() statements, and in case of the same images were picked, it would miss an image.

Flickr image puller.
This script pulls random images from a flickr account, and changes the src of any
image tag, with the class flickr-img, into the src of the randomly picked image.
The script also sets the alt tag to the name of the picture, to be HTML compliant.
The script also won't allow the same image to be picked twice, unless there's
no more pictures to pick from.
