You can add images or other supporting files to your contest. It is advisable to provide as much information as you can so you can receive the best entries from designers. On the Start a Contest page, you will see the + Add Files button. You can click on this button to add images or files to your contest before posting it live on the site.
The maximum file size you can upload is 20 MB. You can upload any of the following file types: spreadsheets, word documents, image files (JPEG, GIF or PNG) and videos (MPEG).
If your contest has already been posted, though, and you’d like to add images later, you can still do so. All you need to do is go to your contest page and click Edit Brief under your contest brief.
You will then be taken to the Edit Contest page where you will see the + Add Files button. Click on this and a window will appear. You can now select the files or images that you want to attach to your contest. Another way is to drag and drop the files to the same area from your computer’s browser.
Once you have finished uploading the files, click Update Contest and you’re all done!
