2) also i notice there is no button to remove an image, i saw another post someone put up about figuring out how to do it but he mentioned a few files that doesn't exist in the later version (installed your webauction this week) March 20th 09 i think
Download the latest version of Xataface, and replace your current 'dataface' directory in your webauction install with the latest xataface. That will include the feature to delete an image.
As for question 1, the key is to make a change to the product details template (in the templates directory) to open a new window with the image... don't have the template on hand to show you source sample --- let me know if you get stuck.
