Discussion and image earnings are now combined as participation

'Image earnings' refers to the earnings one can make from adding relevant images to one's discussions, responses and comments and to images uploaded to the Interests sections. At the moment, you will only be able to add images to discussions you start and to Interests sections. Once you reach a User Rating (the number in brackets by your name) of 500, you will also be able to add images to responses and comments. The note that says that 'Discussion and image earnings are now combined' is there because, at one time, they were shown in separate columns in the Earnings page. Before adding images, you must read the Photo Guidelines here: http://www.mylot.com/o/photoguidelines.aspx and you will find more information, especially about any problems you may encounter, in the FAQs under "Photos": http://www.mylot.com/o/faq/faq10.aspx Rewards are occasional 'bonus' payments which may be made from time to time. At the moment they are only awarded for using the Search facility. Read the FAQ section on "Rewards" here: http://www.mylot.com/o/faq/faq24.aspx

It means that you can earn money if you attached a picture on every discussions you will start. It will make your earnings bigger than the normal posting. You just have to have a full ownership of the picture or you own the Copyright of the picture you will post.
