Some surveys that you complete require you to upload attachments. There is an Upload Image/Document button found either on the very bottom of your survey or next to particular questions within the survey. The location of these buttons will vary depending on the type of survey that you are completing. Click the Upload Image/Document button to attach something. Click Choose File to find the image or document from your computer. Repeat this step for multiple uploads. Once you have chosen all your files needed, click Upload. Verify that the files properly uploaded to the survey.
Do not hit Submit Survey before you have verified that all of your images or documents have attached or you will lose them.
