The Image Upload item allows respondents to upload an image as the answer to a question. Note that the item will only accept image files.
Note: The media capture items (image, video and audio) can only be used for interactive capturing of the content. It is not possible to copy content from one question to another, and it is not possible to copy content between surveys. You can however pipe answers back to a respondent during the interview.
The question details page for this item includes a number of fields and options. All the properties available for this question type are described in the Question Properties documentation (go to Accessing Question Properties for more information).

Set up the question title and text as for any other question.
When the respondent arrives at this question, he/she can then browse to the image he/she wishes to upload. Photos can only be uploaded on supported devices and browsers. The maximum size of an image file that can be uploaded is 1024kb, with dimensions 960 x 960 pixels, maintaining the aspect ratio. These limits are configured for the Forsta installation, so cannot be changed, and are set so that respondents don't experience delays.
The image is uploaded to the server on which the survey is located. When the respondent can see the thumbnail image in the question, the image is finished uploading. Only one image file can be uploaded in an item; if the respondent attempts to upload a second file, the first will be overwritten.
Note that a number of restrictions apply:
- This functionality is not supported for Internet Explorer versions less than 10.
- This functionality is not supported on Windows phone devices.
- The Image Upload question type is never mandatory.
- No scripting check is run to check whether the device is supported, and there is no fallback mode.
- Images can be exported as ZIP files, set via Survey Data export for delimited text file exports.
Note: If you are using the required version of Internet Explorer but your browser is emulating an earlier version, the Image Upload functionality will not run. In this case you must enable the "Use newest available version of IE rendering" property in the theme that you are using.
