A white border added to my original image using contact sheet II

[JWangLu]

When I used `Contact Sheet II ` to splicing many pictures into a grid-shape picture,  I got the correct layout result, including the spacing distance between 2 pictures, but a white border was added to my original image, just like this:

The borders were added at bottom and right. If I copy and paste the original picture, no border was added!

Why I got a image like this? Is there due to wrong parameters? How could I slove this problem?Thanks a lot!

Flatten the image first. You sometimes get that when resampling a floating layer.

Thanks, but how to flatten image in Photoshop or is there any other tools I need to use?

Open upper-right dropdown menu of Layers panel and click Flatten Image.

My original image is a tiff, which just have one layer. I don't know how to flatten on that? I have tried to flatten the contact sheet image, but the border is still.

If you want to tile you  different Aspect ratio image without any white boards added you need to use a script that will resize your images to a common tile size that will  be virtually cropped foe the tile aspect ratio,  a Script like my PasteImageRoll

right click this link and use Save Link As PasteImageRoll.jsx

Thanks, but my images is the same size. The white border appeared on my original image, instead of the gap.

There are boarders on you original image because they are fitted to a rectangle area the has a different aspect ratio than your images therefor  there will be boarders on two side of your fitted images. Images that have the same aspect ratio of the rectangle are will fill the area.   The ContactSheet II script  does not  rescale distort crop you images. Portrait, Panorama, landscape, Croped images  all retain their aspect ratio  when ContactSheets II fits your images to its Picture grid.  Read about my script here http://www.mouseprints.net/old/dpr/PasteImageRoll.html 

My Script does not create multiple documents like contact sheet II,  It create a single document with all images tiled and masked over the canvas. Images  have their original aspect ratio but are masked to the tile size, you can tweak the virtual crops by moving the masked layer image content. The masks are not linked to the image layers they mask.

Excellent script, JJMack! I have tried your script, and the white border disappeared! But my aim is to contact my experiment images, rather than print on roll photo paper, so could I modify your script and only use to finsh our contact sheet? Thanks a lot!
