gallery2 lightbox slideshow troubleshooting

I am facing some issues in my gallery2 module on my website. <[login to view URL]> on the above link, check for the following Lightbox - the popups which come on clicking image thumbnail 1. IMAGE TITLE FREEZES AFTER PAGE CHANGE 2. SOME IMAGES SKIPPING - NON UNIFORM TIME ON EACH IMAGE 3. FRAME DISTORTION (attached screenshot) - specially if i leave play button on, and then restart, it plays automatically and frames start getting distorted sooner. Slideshow - activated from slideshow link on top of page 1. ONLY SHOWING IMAGES ON CURRENT PAGE - that is if 60 photos in a album and 25 on page, it will show 25 images 2. actual slide duration is not less than 7-8sec, even if I set 1 sec in JS 3. jerky transitions, need to smooth/fade them If you are expert in javascript and can fix these problems, please contact. Please note for correcting javascripts, filenames/variable names should not change, only code errors must be rectified. Alternately if you can install a improved versions/softwares (without these errors) on my gallery2, that is also acceptable
