How To: Use images 

We cover a lot of ground in this article!


Adding Images to the Photo Library

1 Adjust the image filename:
    - Only lowercase letters

    - No spaces 

    - Example: underscores_as_spaces.jpg


2 Optimize image:

  - We recommend the image be square or close to square

  - Optimal file size is 300x300 pixels

  - In order to enable larger sizes for images, you'll need to use "_LARGEIMG" at the end of the analytics code. For "Text Entry" question types, the analytics code "_LARGEIMG" needs to be added to the question analytics code. For "Single Selection" and "Multiple Selection" question types the analytics code "_LARGEIMG" needs to be added to the answer analytics code.


3 Drag the images one by one directly from your folder into the "survey images" field:
