S_Merge is a versatile tool for merging up to 8 images or text.
Useful for inserting a watermark in your pictures.
S_Merge is not just about overlaying images, there is an easy to use collage box to allow setting of images side by side and top to bottom in any order.
Optionally apply individual pre-merge image options such as cylindrical panoramic projection, overlaying a dotted and/or a solid line grid on to the image, pincushion/barrel distortion correction, skewing and trapezoidal distortion.
Once aligned there are many ways to merge the images before saving all of part of the target image to a file.
