Ajaxian Theme photo more width & thumbnail Right

Hello, I am trying to personalize magnify theme Ajaxian, when entering the gallery the images are seen by defect not very great, I have changed in thumbnail-functions.js MAIN_PHOTO_WIDTH = 460 by 625, now I am that the inferior part of the photography leaves underneath thumbnails, as I can form it so that they leave to the correct distance.

Also it would please me to know how if thumbnails can be put to the right like others themes, to be able to see the images but great the possible thing in old monitors.

There is some way of which when entering it begins to auto play photos without having to press play with mouse.
