When you upload your images on the submission page, you won’t see them in the current gallery pages until they are approved by the competition admins. Also, make sure you select a category for you images, otherwise the admins won’t even see them for the approval process.
Under the new 2016 competition rules there is only a Beginners class in the Color Category in all other categories Beginners are included with Advanced in a new “Mixed” Class. When viewing galleries you must select the “mixed” class for Mono, Creative, and Documentary entries. If you select advanced or beginners for those categories you will see “This competition did not occur or has yet to take place.”
