Thank you for the reply

1  I opted out in 2009- If I actively opted out -as was the option in 2009 originally - surely that opt out should not be overridden or turned into an opt in without my consent? 

2They are not identical  - I am selling clothes which are similar but not identical - when I questioned this image inconsistency  I was told by Ebay that the onus is on the person using my images of my unique - individual items to make sure they were exactly the same. But they are obviously not identical so how and why can they be shared? 

3 watermarking - I was then told to watermark my images - but Ebay specifically requests that you don't watermark your images - I think for advertising off site. 

4 copyright - my photographs - the images I take - are covered under UK copyright law and dont need to be watermarked to be copyrighted. 

5 proving ownership of images - Ebay also said I cant prove these are my images without a copyright watermark-  which is untrue - I can prove these images are originally mine. 

It would be helpful to have a direct response from Ebay about these individual points 1-5 - as I am really confused - especially as there is a record of my opt out in 2009.
