Hi,
in my opinion your post is a bit confusing.
First you say
and I want to use them to appear in random order
Here you would use "Randomization group name",.
The images and the set of questions appear in random order.
But than you say
I just want to load one random image from that 10 images
This you would do by creating a random number and display either the group (image + questions) by relevance equation or you create only one group and insert the image by an IF-statement.
I tried to use scripts that I found here but it doesn't work
What do you expect us to say, if we do not know which scripts you tried?
Pictures can't load from server.Is there any simple way to fix it?
Of course not. We have not the least idea, what you are doing, how you try to load the images.
And please, the first and most important information always is: Which version of LimeSurvey are you using?
So you should provide a lss export of your survey, that we see better where there are your mistakes.
