You can upload unlimited number of files with all paid licenses. However, depending on your license level there is a limitation on the total file size.

• The Image/Multimedia file should be less than 1 MB in size. For better accessibility on the survey we suggest that you use smaller file sizes.
• The default width of the survey is 750 pixels. Upload Images/Multimedia files smaller than 750 pixels.

We've had a lot of users abusing this feature by uploading and hosting images from our servers. So we've disabled this for all the free licenses. If you need to upload images, logos and multimedia content, please upgrade to one of our paid licenses.

Alternately you can also refer to images / files uploaded on any external servers / file sharing platforms using the URL provided for the file.
