It's like you had one large picture and you cut it up into 6,800 little squares. I only have the little squares, not the original, and I want to put them together without any seams showing to make the large original image. They're numbered in sequence, they must stay in the exact sequence, and I already know exactly how many rows and columns the composite needs to have. If it's easier in some other program than GIMP that's fine too.
1. Open GIMP and create a new blank image that is large enough to fit all the small images together.
2. Go to "File" > "Open as Layers" and select all the small images you want to merge.
3. GIMP will open each small image as a separate layer. Select all the layers by holding down "Shift" and clicking on each layer.
4. Go to "Image" > "Configure Grid" and set the grid size to match the size of your small images (256x256 pixels in this case).
5. With all layers still selected, go to "Layer" > "Distribute" > "Distribute Layers" and select "By Grid" from the drop-down menu.
6. This will align all the small images perfectly on the grid. You can now merge all the layers together by going to "Layer" > "Merge Visible Layers".
7. Finally, you can save your new large image by going to "File" > "Export As" and selecting your desired file format.
