Teespring/Sunfrog - editing t-shirt image when promoting

[Matijal]

Hi guys,

I have a website where I would like to sell t-shirts and earn from affiliate sales. Can I copy the t-shirt image from Teespring/Sunfrog website, upload it to my server and promote it from my website? Also, am I allowed to change background of that image, from white to grey for example, crop it and resize it so it would fit better to my website? I would not alter the design of t-shirt. Would that be a copyright or some other violation of terms or something? I can't find anything about it in their tos.

I think you would be better of creating your own designs and get the full royalties. That's what these POD sites are for right?
