/* Text and/or Image Crawler Script v1.53 (c)2009-2012 John Davenport Scheuer as first seen in http://www.dynamicdrive.com/forums/ username: jscheuer1 - This Notice Must Remain for Legal Use updated: 4/2011 for random order option, more (see below) */

/* Update 4/2011 to v1.5 - Adds optional random property. Set it to true to use. Fixes browser crash from empty crawlers, ad and image blocking software/routines. Fixes behavior in some IE of breaking script if an image is missing. Adds alt attributes to images without them to aid in diagnosis of missing/corrupt images. This may be disabled with the new optional noAddedAlt property set to true. Internal workings enhanced for greater speed of execution, less memory usage. */

/* Update 11/2011 - Detect and randomize td elements within a single table with a single tr */

// updated 7/2012 to 1.51 for optional integration with 3rd party initializing scripts - // ref: http://www.dynamicdrive.com/forums/showthread.php?p=278161#post278161 // updated 8/2012 to 1.52 for greater compatibility with IE in Quirks Mode

/* Update 10/2012 to v1.53 - Adds optional persist property to have the crawler remember its position and direction page to page and on page reload. To enable it in the marqueeInit set persist: true, */
