I can not upload photos in the form in frontend

I can not upload photos in the form in frontend.
In the backend, it is easily possible.
Is there a setting to do? or conflict?
Who has had this problem?
thank you

# example of recommended settings
post_max_size = 8M
upload_max_filesize = 8M
max_execution_time = 60
