You do not need a new script. All you need to do is create a PSD template adhering to my four rules. They are very simple.
The Four Rules:
- Size the photo collage templates for the print size you want - width, height and print DPI resolution.
- Photo collage templates must have a Photoshop background layer. The contents of this layer can be anything.
- Photo collage templates must have alpha channels named "Image 1", "Image 2", ... "Image n".
- Photo collage templates layers above the background layers must provide transparent areas to let the images that will be placed below them show through.
One does not simply pop out a complicated script. Look at my scripts with a text editor there is a lot of design and programming involved. I have no idea of what size and resolution you want your collage to have. I also have no idea of what your images aspect ratios are. With that knowledge it should only take a few minutes to create a template fewer the ten for sure.
I created a template for you latest example using its size 30" x 12" at 200DPI and the 6 different aspect ratio images. There is still some tilt in image 3 and 5. You can download the template http://www.mouseprints.net/old/dpr/6images.psd
I only used a Background layer. I did not add and upper overlay layer however the alpha channel I created for image 6 will let some of the background show through image 6. Here is a screen capture with the Template in Photoshop and under it a populated version. Also just copy my scripts into Photoshop folder Presets\scripts and use them from Photoshop menu File>Scripts>My Script Selected. The extendedscript toolkit has problems with some things.
