Combine multiple images into a long image grid
Combine multiple images into one and output it as a JPG, with three layout options:
Setting the spacing to 0 creates a seamless stitch, which works well for joining long screenshots together; increasing the spacing makes each image stand on its own. Both the gaps and blank areas are filled with the background color, and these two settings largely determine whether the finished result looks like a polished piece or a casual mashup.
If the photo sizes don’t match, the grid will leave gaps that are filled with the background color. For the neatest result, first crop the photos to the same aspect ratio before stitching them together.
