I would like to add the company logo to the survey. Please let me know if I can add this with the basic feature. I have fine with the survey I have build just want to make it more professional and appealing to the employees completing the survey by adding the logo.
The Basic License does allow you to add a logo image (though this is limited to externally hosted images).
Rather than uploading your header image to your library (no library access on the Basic License), you would need to use the Image URL field described here:
This means that your header image must be hosted somewhere online (you essentially need a link for the image that you can paste into the Image URL field).
I hope this helps clarify!
