Hello,

I'm building a questionnaire and I would like to know how to display one picture on a page for 20 seconds before automatically switch to a new page.

Thanks

I think you need some jQuery to do that. The following code will auto submit the page after 20 seconds. I didn't test it. If you want, give a try.

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
setTimeout(
function() {
$('#movenextbtn').trigger('click');
}, 20000);

});
</script>

I do not understand how to put the picture.

It worked. Thank you. You know how to remove the "next" button on this page.

Thanks. Its Work.

Document ready can trigger before images are loaded. It's recommended to use $(window).load since this will fire after everything including images have loaded. I have experienced this issue once on a survey with a timer for images. Got a few complaints that they didn't get to see the images before the page auto submitted. I too was using document ready. This stackoverflow post talks about the difference. stackoverflow.com/questions/544993/offic...e-executing-somethin

Use $("#yourimage").load
