Direct Answer: How do you stitch and merge JPG images into one picture?

The most efficient way is client-side canvas stitching. By utilizing HTML5 Canvas directly in the web browser, multiple JPG or JPEG files are composited side-by-side, stacked vertically, or arranged in a 2-column grid without uploading image files to external servers or suffering lossy recompression artifacts.
