Creating a collage for images makes sharing more fun, promising to preserve a wealth of memories. A number of tools are available that do the job very well.
This post describes how to create a collage maker with Cloudinary. It took me a while to learn Cloudinary’s advanced implementation techniques, such as variables, the upload widget, unsigned uploads, tagging, and resource listings. No worries, however; many excellent references are at hand, e.g., this article by Cloudinary Support and the Cloudinary Cookbook.
