Before the problem you are saying, if you open this CSS:
galeria.o2switch.net/tit/templates/bt_bazaar/css/virtuemart.css
And find this CSS Rule:
div.productdetails-view div.main-image img { width: 240px; }
and remove it. Then the TRANSITION effect when you click the thumbnail, will look much better. Just try it, you would love the result.
About your other problem. Again you should look at the SAME CSS, which is this:
galeria.o2switch.net/tit/templates/bt_bazaar/css/virtuemart.css
And find this CSS rule:
div.productdetails-view div.addtocart-area div.product-fields div.product-field span.product-field-display { width: 65%; float: left; }
and change it with this:
div.productdetails-view div.addtocart-area div.product-fields div.product-field span.product-field-display { width: 65%;}
the result will be:
Cheers.
