Hello,

if you have a question please put it into the post and tell us what is your problem or what you want to do.

Like Shnoulle said there is no perfect sollution to prevent people from "copying" something from your page/survey. You can just make if more difficult for them, e.g. you can use a background image instead of "normal" images, add a watermark to an image, write text into an image so people can't copy the text directly, do some funny things with Javascript, ... .

Regarding copyright issues you can e.g. add a copyright notice to your survey template to tell people what you want to tell them.
Mit freundlichen Grüßen/Best regards,

Thank you very much.
However, how to use a background image instead of "normal" images. I can not use Javascript, I have not learned it.

Hello,

you can use CSS/Style Sheets to add a background image to an element on your page. Let's have a look at the limespired template. There you have an image with two trees in the header. The "header" in the example is a <div> Element
<div id="header">
. In the template.css file you will find something like
div#header {
  background: url(header-bg.png) no-repeat;
  right-bottom
}
This adds a background image to the element and uses "no-repeat" to prevent the image form repeating itself.

I don't think it is very difficult to do add a background image, if you have further questions or problems it might also be a good idea to search the internet for more information.

There are many pictures in one question, can I use different pictures as background images in one question? Furthermore, How to control the location of different images?

You can only use one background image per element and position it with the background-position propery - www.w3schools.com/cssref/css3_pr_background.asp

Yep,

Maybe, but all image still dowloaded via the cache in the user computer.

(ANd it's very easy to access to background image too).

There are no real possibility to do that.

I agree with Denis, this is also not very secure.

I was just pointing out how to position the images.
