Can I make three separate submissions? I wish to submit one entry now and the other two later. Will I be prevented from logging in later?
You could log in later by using your email address and password.
How long does it take to upload a file?

Uploading of images depends on image size and your internet connection however, shouldn't take longer than a few seconds (or minutes for an MP4 movie if you submit to the multimedia category).

Have loaded up two images, one does not have a thumbnail, does this mean I did something wrong?

If the file does not comply with the requirements it will not load to the system and there will be no thumbnail showing.

Images have to be saved in jpg format (or MP4 for multimedia) and named correctly using only letters, numbers and under scores; any other symbols may cause the upload to fail.

I am unable to register. This is my second year applying- so my details may be stored from last year. 
When I try to register, and fill in all my details, the next page asks for name and password, and then says 'invalid password'.

You have to register on the site with your details in the first stage of the submission. Please check under "my account" that your details are up to date.

Once you register, you will be able to log on again using your user name and your nominated password (password can be any number of letters and/or numeric characters) to check on your entries.

I have received emails from head on does this mean I am registered to enter?
No, you have to register on the Head On website as part of the process of submission by entering your contact details.
I have tried several times to upload my photo. In the "image uploader" screen the little whirly sign comes up to say that something is happening, but even if I wait 15mins or more, no thumbnail comes up. Is the image uploaded?

When Images are loaded to the server successfully, you get to see a thumbnail of the image and a message indicating it's done. The 2 reasons the process is not successful are: the file name has 'illegal' charaters (space and symbols other than letters, numbers and under score) or the file format is other than JPG or MP4.

I did not add a description after uploading my images, Can I add a description?

You need to add the description BEFORE paying for your images. Once you've paid, the images get locked and you will not be able to make any changes.

I'm trying to submit entries, but I'm prevented because I don't have a mobile phone/land line? What can I do about it?

Please enter your landline/mobile number again.
 Please note, you cannot have any symbols other than numbers and under score (no spaces allowed).

I've uploaded two images but I want to delete them and start again. The images were wrongly named and uploaded the same image twice. How can I delete them?

Once logged in check the images you uploaded under "submissions". On the next page you’ll be able to delete the image.
 Bear in mind that once you pay for your submission, the images get locked and you will not be able to make any changes.

My login doesn't work and I get this error when I try to use the forget password field, any ideas?
You have to register on the site with your details in the first stage of the submission.
 Once you register, you will be able to log on again to check on your entries.
When uploading images I do not get the thumbnails to confirm receipt. Does it mean that the images have not uploaded?
If the images are loaded correctly, you will see a thumbnail of your image.
Why does the message "non-numeric number" keep coming up when i try and fill out my details in the phone and mobile columns?

The system checks that you enter only numbers into the phone/mobile fields.
The accepted characters are numbers and dashes. You cannot have spaces.
 A Sydney number will be entered as 02-91234567.
