poster tiling with photo library

My script just tiles out  images on to a Canvas. You specify the canvas width, print resolution, and tile size. Also you can specify margins and spacing between tiles.  You can select any images you want and you need to select the correct number of images the fill the canvas size you want filed.  You need to do the math so the tiling will be what you want. Only rectangle tiles will be laid out.   You can change the Default by editing the script. The Default are in Inches for I reside in the USA. The paper width defaults to 16"  one copy of each image to be tiles. the resolution 300PPI.  The max length default to 100' You could set the length the paper size you have. The Script will however calculate the canvas length  using   tile size,  margins, space and the number of image you select.  If you select more then will fit onto the length the script will not tile it will give you message that you selected too many images.   Your images will also be resized to fill the tile size specified. If the Aspect ratios are different from the tile size aspect ration. The images tiled  will look like entered crops.  The tiled images be in a layered document. So before you print you can tweak the images compositions by moving the layers image content.  Images are mot actually cropped they are masked to tile sizes the images are not linked to the layer's layer mask.  Though The dialog is set for inches. Its just numbers.  The script does everything using Pixels like Photoshop. Everything is relative to resolution set. 300PPI  so the tile 4"x6" is relative to the 300  resolution set. 1200px x  1800px  So the Dialof is mectric with the right resolution.
