Call me stupid but amazon images confuse me

So I have read that you should use siteStripe if you want to use amazon product images.
But how should I put the img alt attribute?
For example this is my image code from siteStripe

==============
<a href="https://www.amazon.com/adidas-Mens-Response-Metallic-White/dp/B01J461QWQ/ref=as_li_ss_il?keywords=golf&qid=1564721011&s=gateway&sr=8-5&linkCode=li3&tag=XXXXXXX&linkId=XXXXXX=en_US" target="_blank">
<img border="0" src="//ws-na.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=B01J461QWQ&Format=_SL250_&ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=XXXXXX&language=en_US" ></a>
<img src="https://ir-na.amazon-adsystem.com/e/ir?t=homeipcame-20&language=en_US&l=li3&o=1&a=B01J461QWQ" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" />
==============

As you can see there are two img tags and the latter comes with alt="" automatically.
What I want to know is which img should I insert the alt? The latter is just a pixel?
When I paste the src of both it doesn't even show any image.....

Thanks

You want to add alt text to the first IMG.
