As answer choices?
Which question type do you use?
"image-select"?
Try to add the folder of your LimeSurvey installation like /lime3/upload/surveys/761949/images/Boot001_klein.jpg
And in "image-select" don't use the <img> tag.
Styling in custom.css or inline.
Or do you use normal "list(radio)". Then you have to use the <img>.

Volunteers are not paid.
Not because they are worthless, but because they are priceless
This is the result, if you do not tell us the important informations, that you don't use the Community edition, but the LimeSurvey hosted edition.
Okay, as I said: Styling by css.
You may have a look at the "imageselect.css" in the respective folder and investigate by a webdevelopment tool (included in each browser)
Here I used a class "my-image" in the question
and this in "custom.css"
