I will show a image to participants together with an brief instruction above the image. I want to keep the font of words in the image the same/similar with the instruction font. But adjusting the size of the image by changing the width and height works in the edit layout but not in preview, so no matter how I changed the width and height of the image, the size did not change in preview. Just like below, the words font of the image (i.e., Please indicate the extent to which ......) is always smaller than instruction font (i.e., Below is one of ... a bonus of $5).


I really appreciate that if anyone can give me some clues to fix this problem!
