Update ideal-image-slider.js

Ok here is problem. first i need to pass "rel" attribute, then about 3 hours, i tried to find what wrong with internet explorer (10), so i found if  u clean sliderEl.innerHTML = '';  element before main loop, all elements inside is fked up, and <a><img></a> slides not work anymore. so i move cleaning and adding elements after the main loop. now it's working. thanks. i also write iis-thumb-nav.js (used small thumbnails instead bullets) module but don't know how to send it to you.
