Adding a second image to a fluid box
I have been trying to add a png image from the library to a fluid box that already contains one image. Instead of adding the image and resizing both images, this move overwrites the original image with the new image. If I want to get the desired result, I have to drag the image from the library to another (empty) fluid box and then drag it into the desired fluid box. I feel like I'm missing something really simple, but I don't know what. Please help.
