When designing your website, don't make it hard for people to see the Buy Buttons on your images.
We understand the dilemma here - you're a visual artist, and you want your visitors to be focused on your art, while making your site visually-pleasing with minimal distractions; you might even think your Buy Buttons should barely be noticeable!
Not to suggest that you go off and make huge Buy Buttons with blinking fonts, rather we encourage you to not forget why you put Buy Buttons on your site in the first place, and think of ways that you can design conventional, tasteful and *visible* Buy Buttons in to your layout.
Your visitors might want to buy your images, and it's a good thing that you let them see how =)
