Modular Photo Collage Template

About This Piece
This modular photo collage template was created for the FOCAL (Free and Open-source Creative Art Library) project during the FOSSEE Summer Fellowship 2020.
The Objective
To create a reusable, stylish photo collage template that allows users to easily drag and drop their own photos without complex editing.
- Download Template: You can download the source file from the FOCAL Library.
- Tool Used: GIMP.
The Design Technique
The key feature of this template is the use of layer masks and clipping groups in GIMP. Instead of manually cropping each photo to fit a shape (like a diamond or circle), users simply place their image into a specific layer group, and the template automatically masks it to the correct shape. This makes the template highly reusable and user-friendly.
The Tutorial
I created a tutorial to demonstrate how to use this masking feature to quickly populate the collage with personal photos.
