Adobe Illustrator has nice features that I miss in Photoshop. One of them is Transform Each. When you need to transform group of layers, it transforms each of selected layers as it was transformed individually.
You need to resize each userpic in 50%. If you’ll select all of them and transform it via default Transform Tool
Not cool. Alternatively, you can choose each image and transform it manually. This can be tedious process. So, here comes Transform Each, it transforms each of selected layers as it was transformed individually
In our case, script resized each userpic in 50%, and moved it top right in 20px.
