The copyright of the picture on the club website remains with you unless you agree to them using it with all rights of publishing and copying. You still retain the copyrights though
This may only mean that no-one can copy a picture from the website and re-use it elsewhere, it may not mean they own the publishing rights of that picture which will remain with the photographer to do with as he pleases.
