How can I erase part of an image
Hi, I am trying to overlap some images like below on Illustrator but as they have a white square box around them part of the trees is missing when I have cropped, copied and pasted on to an art board. I tried to use the eraser tool but it is not allowing me to do so. Is there a way that i can do this please like Photoshop maybe where you have a selection tool to go around the edge of the objects eliminating the white you do not need. Many thanks.
