Sorry, I really wanted to share this, even though I wouldn't really call this an "image." Enjoying character design and creating model sheets, I thought I'd make a PSD template with pre-measured "head" units (inspired by Tim's excellent model sheet tutorials.)
The file has nested folders, providing measurements for multiple head counts, from "3 Heads" to "10 Heads," and is split by Front, Back, and Side with a vertical center line for each.
It can be downloaded from here:
