E-commerce

Hello, trying to create an e-commerce site for downloads very much like a boutique stock agency. I purchased your pro version and hope I can get support for these items as I finetune the presentation to customers. I have a couple things I need help with and have searched and do not find answers in forum:

1. the way it is written you have to click the shopping cart icon to bring up the ADD TO CART menu etc on the right side of the photo. I would like that to be up there all the time without having to click the button. Is that a possibility? Can you advise how to change that?

2. Also the e-commerce lightbox is very slow to scroll to load. I only sampled it with 6 images. It hesitates and shows a little ring with dots. How can I speed this up?

3. Most of my images are vertical – what presentation gallery do you recommend that would be best for this?

4. I would like my manufacturers to see what size the original image is, the camera used to take it, the tags associated with it and more. Is there a way to display the metadata, tags and camera data in the e-commerce lightbox or galleries? Please direct me how to do this?

5. Considering purchasing the advanced search bar. Will I be able to place it on the front page of my theme? I can not seem to figure out how to do that with the free version. IS there a way?

6. Can’t get watermark to work. Everytime I go back to watermark it is defaulting to “use image”, even though I saved it and told it “text”! There is no watermark showing on my images in the gallery..

Thanks for your help.
