Basic Data Migration must know how to link images in joomla

This should be a straight forward copy and paste but we will need to move all images to the new server and relink them. We need to move over all products from existing site and move them to joomla. I have a video explaining the project if you are interested please pm me. Again I need this done quickly but I will first have you enter 1 product into each category and section to be sure all is correct before doing all other products. This should be easy for anyone who knows computers and data migration. Please pm for details
