Answer 1

testName and the others may need to be updated via innerHTML
function volgendefoto() {
if (++currentPos >= images.length)
currentPos = 0;
img1.src = images[currentPos];
testname.innerHtml = testname[currentPos];
testjob.innerHtml = testjob[currentPos];
testpa.innerHtml = testpa[currentPos];
}
