Joomla Shopping Site (2)

Hello, We have a Joomla shopping site for a computer supplier ([login to view URL]) and need these changes made: 1) They want a quicker way to update the PC & server prices on the website. Presently they have to manually update around 40 or so items manually every time the prices changes. They want something that will update all the prices in a category if there is a price change for something like a hard disk or memory. 2) Bug Fix: Still not getting thumbnail option when adding a product image (this used to work but stopped after a while, when I add an image to a product it used to automatically create a thumbnail image, but now I have to create a thumnail manually. It slows down the updating of products) Thanks Dave Geoghegan [login to view URL]
