Album Action Menu customization help

I am not very php savy, but I do know how to use the editor my question will require step by step answer in easy english as I am pretty new to all this. I've set up my gallery and zencart together and its working great. My site is a photography site. What I want to do is make the album action drop down menu into a single link called "Purchase Image" and this link would take you directly from my image in the gallery to the image in the store when you click on it. Ie: no drop down menu would be seen by the customers just one word linked up to the store sort of thing.

Right now it shows "Basket:View Items" on the album pages and it's linking directly to my main store page which I don't want. I don't want the links to show up at all on the actual albums, when you look inside the album at the images, I'm seeing the drop down menu for each image-this is where I want to see the "Purchase Image" link.

Images in my album:

Album itself:
http://www.sandraadamson.com/photographystore/main.php?g2_itemId=21

Could someone give me step by step easy instructions A-Z kind of thing to help me do this with my gallery. I've looked all through the gallery and I've not been able to find a question quite like mine.
Hopefully I'm being clear here like I said I'm very new to all of this.

Thanks so much
Sandra
