Amazon has become really strict about the use of product images. We can no longer download product images and then upload them, use our own html to make clickable images, etc.
We have to use the HTML codes for product images that are given to us by Amazon.
To do otherwise, could get your account closed with Amazon. They have been pretty busy lately shutting down Associate accounts.
Those who also participate with Whyrll. The way members have to add Amazon product images to the site is against Amazon TOS.
There are those who think some have been grandfathered in and are safe which is incorrect when it comes to how we get Amazon images on our sites, on sites like Whyrll, etc.
