What do you mean? The possible themes for photography (competitions)? You can take a look the many other theme competitions by other forums and get your inspiration from there. Not possible to list out all.
Have you had a look into them? Every photo has a theme, more or less well worked out by the photographer. Go along that lines and develop your own theme that you can use. You can check the previous photography competitions here in CS or the Canon Photomarathon. Plenty of themes.
Are you by any chance using Google translator or something similar? This sentence doesn't make any sense to me. I could guess, but you rather expect answers, right? Please form a clear English sentence so that we can understand what you mean.
