when i add a product document, in the form tab of this product document, i upload a big photo, then i upload a thumbnail photo to a file folder of cmsdesk, in the product tab of this product document, i upload this thumbnail of this product and save it. however,the product tab's photo is still the big photo, i have to re-select the thumbnail and then save it to show it correctly. another question is when i use corporate site, the product of cell phone and labtop's image url is /getattachment/****/Nokia.aspx, if i want to change a picture, the url becomes /getfile/***/Nokia.aspx
