This may be old news to some of you but as I'm just really getting my feet wet here with Amazon (a resource that is a god send), but in researching how others set up their sites (off wizzley) I'm seeing some interesting developments.
Soo... Some tips I discovered:
1. if you can't find a good image that pops on your article in full width mode, go back and see if any other sellers are offering it. Some sellers upload crappy images, others large vibrant ones... never just stick with what you find first!
2. My choice is this one, go to amazon and look through a products images for the product. You'll find often the one that becomes the image for the ad on your wizzle is not always the best one (what the hell right? makes you want to send an email to these sellers, but there are too many of them!)... I find the best high resolution image for the product found on the ad and save it, upload it into an image module, use it as the "display" piece for your amazon ad, below the image you can put the list ad for the product. or you can get creative with putting up a gallery image and side by side it with some text (text module) to give it a proper welcome (but stay away from sales speak).
This is also a great way to get it to line up seamlessly with your content. You can actually throw an amazon ad up there with absolutely no clues that it's an ad other than a super light grey "ad" text on the bottom right... Share your ideas people I'm ALL EARS/EYES.
