Image select multiple choice shows each option as a picture with a checkbox in its corner. Participants click every picture that applies. Use it for designs, products, places or anything people recognize faster by sight than by name. For one picture only, use List image select (Radio).
Click the purple + in the top bar. The question type picker opens.
Under Multiple choice, click Image select multiple choice. The question appears at the end of the current question group.
Click Your question here and type your question.
Each subquestion shows a box with NO IMAGE. Click the box and select a picture from your computer, as PNG, JPG or GIF.
Add subquestion below the last picture adds another option.
Select the question to open its settings on the right. The picture settings are under Advanced > Display.
Exactly as for Multiple choice: every picture is a subquestion stored on its own, for example Q012_SQ001, with Y when it was selected. The export does not contain the pictures, so note which code belongs to which picture.
Lower Fix height, or turn on Horizontal scroll so the pictures sit in one row.
PNG, JPG and GIF. Use pictures of the same size so the options look alike.
