Would it be more natural for the user to click under the text area or in a centralized area of actions.
In our example at http://www.bruxzir.com/science-bruxzir-zirconia-dental-crown/, we have images on the left and text on the right.
The button to download a larger image are under the image, which makes sense to though I am encouraging to just use a larger image to begin with.
The site was originally designed when internet speeds were slower, so the first designer wanted to be mindful of load time.
The "download image" makes sense on the left. But so far so is the "download report on the left."
So would it make more sense to have all downloads on left. Perhaps as my new mockup below
Or under the content that they represent?
