Join Images features

The Join Images JS module enables you to merge multiple images into a single composite image with customizable properties.

You can specify the space between images in pixels and choose a space color. The join direction property lets you determine whether the images are combined vertically or horizontally. Additionally, you can set the output format of the merged image to jpg, png, or tiff.

The Join Images JS module is useful for creating cohesive photo collages or visual presentations by seamlessly merging multiple images with customizable gaps and orientation.
