S_Merge

S_Merge is a great application for combining up to 8 image files in one document, helping you create complex collages in a quick and easy way.

To use S_Merge, all you need to do is import the image files you want to combine. After that, select the size and position of each one to create your desired composition. You can also choose the background color if that's something you want to modify. When you're done, all you have to do is export the final result, which you can save as an independent image file that retains the original resolution and quality of all the images.

Another great thing about S_Merge is that you can play with simple editing tools. For example, you can modify the shape of the imported images, write on them, or add simple gradients.
