// converted to element ids (of content) instead of images, for solution industries, 15th april, 09 (mainly for linking purposes... but also titles, and seo) 
// when fader is opacity 0 display none so only opacity 1 is present (we have to combine opacity with z-index which can't, so combine opacity with being present or not...)
// also removed all single letter vars and added slide prefix
