Previously every image was bilinear-resized to match the max height/width in the batch, which distorted product photos. Images now keep their original size and are centered on a padded canvas, with empty space filled using the background color (now defaults to white).
Images_Merge_ComfyUI
A ComfyUI custom node that merges a batch of images into a single grid canvas, with configurable columns, spacing, and background color.
Node: Image Grid Merger
Inputs
| Name | Type | Description |
|---|---|---|
| images | IMAGE | Batch of images to arrange into a grid |
| columns | INT | Number of columns in the grid (default: 3) |
| spacing | INT | Pixel gap between grid cells (default: 10) |
| background | enum | Fill color for gaps/empty cells: black, white, gray |
Output
| Name | Type | Description |
|---|---|---|
| image | IMAGE | The merged grid image |
Images of differing sizes are resized to match the largest image in the batch before being placed on the grid.
Node: Image Grid Merger (Upload)
Same merge behavior as above, but you don't need separate LoadImage nodes upstream. Each image_N input is an upload widget (just like LoadImage) directly on the node — click it to pick a file from disk, or choose a previously uploaded one from the dropdown. Only image_1 is required; image_2–image_6 can be left on none to merge fewer than 6 images.
Inputs
| Name | Type | Description |
|---|---|---|
| image_1 | image upload | Required image file |
| image_2..6 | image upload | Optional image files (none = not used) |
| columns | INT | Number of columns in the grid (default: 3) |
| spacing | INT | Pixel gap between grid cells (default: 10) |
| background | enum | Fill color for gaps/empty cells: black, white, gray |
Output
| Name | Type | Description |
|---|---|---|
| image | IMAGE | The merged grid image |
