Go to the “Photos”, “Objects” or “Animations” tabs and click on the image you'd like to add -the image will be added in the middle of the design and you will need to drag and drop it anywhere on the artboard. Photos can also be resized by changing their original ratio- use the side controls to stretch the image as you wish:
Adjusting image transparency and layering
If your design contains a number of layers and design elements, you need to arrange them in such a way so everything looks fine. You can move some of the design elements to front and back or add transparency to create a perfect look. You can change the transparency of all the designs in Crello collection. Everything you do is just move a slider. Transparency can be set from 0 to 100.
