Have a doubt about Amazon Affiliate Marketing!! (Need your master advice)

Hi,

I have read somewhere that when promoting using amazon affiliate network, I have heard that we can only use product images from amazon. Is it true, then how is this person using other images in his blog posts and also promoting amazon affiliate?

Also I have heard that we should always use only amazon approved buttons? How is this person using the button with the text 'Check Price in Amazon'.

Arn't these two stuff against the amazon affiliate terms and conditions.

Thanks,
Ankith

Firstly remove the link, that is not fair on whoever owns that site. You can use any images you want, and you can use any buttons you want. But if you want to use the Amazon logo, you can only do so on their approved buttons.

Now remove the link.

Also, simply read the Amazon Affiliate ToS, it answers these questions.
