You can add images or other supporting files to your contest. It is advisable to provide as much information as you can to receive the best entries from freelancers.
On the Start a Contest page, you will see the + Add Files button. Click this button to add images or files to your contest before posting it live on the site. You can also directly drag and drop the files on this area.
The maximum file size you can upload is 20 MB. You can upload any of the following file types: spreadsheets, word documents (PDF and ODT), image files (JPEG, GIF and PNG) and videos (MOV, MPEG, FLV, and AVI).
If your contest has already been posted though, and you’d like to add images later, you can still do so. All you have to do is go to your contest page and click Edit Contest beside your contest description.
You will then be taken to the Edit Contest page where you will see the + Add Files button. Click 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 finish uploading the files, click Update Contest and you’re all done!
