Hello Lida, to check if you have already your images on the market please go to your profile page and hover mouse over images. When you hover mouse you will get Market availability, and if on all images you have "Yes" then all your images are on the market.
If they are not all on the market, please go to your Market page -
http://www.pixoto.com/settings/market and click on "Add all images to the market" and all images that are not on the market will be added to the market.
If all of your images are already on the market you will get message that "0 images were added to the market".
Please let me know if this doesn't help.
