The Image Upload object allows respondents to upload an image as the answer to a question. Note that the object will only accept image files.

Set up the question title and text as for any other question.

The respondent 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 1280 x 1280 pixels, maintaining the aspect ratio. These limits are configured for the Forsta Plus installation so can be changed, and are set so that respondents don't experience delays.
Only one file can be uploaded in an object. If the respondent attempts to upload a second file, the first will be overwritten. Note that when the respondent can see the thumbnail image in the question form, the image is finished uploading. The image is uploaded to the server on which the survey is located.
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.
To view the images that respondents have sent, export the survey data as "Delimited text file" and in the second step of the process, in the Export dialog, select to Include Uploaded Media Files - .
Figure 3 - Including media files in the data export
When this option is selected, images, photographs or videos captured as upload question types will be included in the generated exported file. This option is only available for delimited file exports. The media filenames are the same name as that stored in the data record for that question. In the event a large number of images are to be exported, FTP delivery should be used.
Note: If you are using the required version of Internet Explorer (as described the System Requirements) (go to System and Respondent Requirementss for more information)) but your browser is emulating an earlier version, the Image Upload functionality will not work. In this case you must enable the "Use newest available version of IE rendering" property in the theme that you are using.
