Okay, so you see the top right hand corner? It has like "submit deviation" And "Submit print" and "update journal" And stuff?
You click on "Upload deviation"
Then, Where it says "Which file?" You click on "add a file" Which is right under the box that has "No file added yet" <If you wanted to upload a story or a text you click on 'submit text' and copy and paste the writing into the box available>
When you have clicked "Add a file" you find the file you want to upload. DA will upload it and in the mean time, you fill in the artists comments and the deviations name and key words.
Also, the mature content, you'll have to click the box appropriate. So, if you're picture has nudity in or anything that could possibly offend other people, you would put a mature content on it. If not, you just select 'no'
When the file has finished loading, it will come up with a little thumbnail of the photo you chose to upload.
If everything has been filled out, you just click on 'submit' right at the bottem
I hope that helped ^^
