Change Log:
Date Version Notes
20131011 1.2.5 *Reposition loaded image on a timer.
20130827 1.2.4 *Revert 1.2.1 since script was corrected by author.
20130804 1.2.3 *Updated rules for video thumbnail images.
20130426 1.2.2 *Changed require URLs to https.
20130108 1.2.1 *Moved the "gm_config extras" script with corrections to anandkumar.me domain.
20120829 1.2.0 *Added @grant directives to comply with Greasemonkey 1.0.
*Removed dependence on custom updater since Greasemonkey now has an internal updater.
*Copied the floating image repositioning logic from my Flickr script.
*Moved all floating image related code to a single class. This is the first step towards unifying my other scripts that use the same logic.
20120606 1.1.0 *Fine-tuned the image positioning algorithm.
*Added "Ctrl" key override to persist preview image.
20120604 1.0.2 *Added support for a delay timer and a corresponding configuration item under settings.
*Added support for the setting the preview image to "Snap to Cursor".
20111112 1.0.1 *Added missing escaping to some reg-expressions.
20111103 1.0.0 *Official release of script.
