Please make sure qeep is properly optimised for your phone model. To optimise your phone, go to "My qeep" followed by "Options" and select "Optimise". After restarting qeep, please check the photo function again. If you still can't take any photos, your phone doesn't support qeep's photo function.
But don't worry, you can also upload a photo straight from your phone's memory. Go to "My profile" and select "My profile picture". Hit the "Upload picture" button to access your phone's memory and follow the further on-screen instructions.
