[Support request] Creatives user instructions for affiliates

I am totally new to this so my apologies if these are dumb questions. (I have read all the documentation and every post on this forum under the search term “creatives” but have not found anything to help or answer my question)

As someone who has not used this plugin before, the lack of a step by step “dummies guide” is a cause of huge frustration. Please can you help

1. When the affiliate logs in and goes to the creatives tab in the affiliate area he sees this:
Your Affiliate Link Using Affiliate ID:
https://xxxxxxx.co.za/?wpam_id=1

My question is whether he must copy and paste this link as is to use in emails etc?
Is there not a version which does not display or show the ?wpam_id=1 which he can use?
If there is, where is it and how do I find it?

2. What is the step by step procedure for the affiliate to extract and use an image creative
This is what you see on the affiliate creatives page:

The following creatives are available for publication.
Type Name
Text default creative
Image test

When I click on the creative named “test” it shows me HTML snippet and the image but nothing is embedded in the image (as far as I can determine) so how does the affiliate actually make use of this ? Step by step please, I am lost! Also is the “alt text” which I entered not supposed to be a part of this somehow?

Thank you for reading.
