Image Grid Pixaroma

What it does

When Load Images from Folder, Prompt Each or a Loop sends many pictures through a workflow, a preview only shows the last one. Image Grid collects ALL of them into one picture, laid out in a grid, so you can see the whole Run at once, share it, or compare.

The grid shows on the node and comes out of the grid output. Wire it into Save Image Pixaroma to keep it.

How to use

• Wire the results into images.
• Wire Load Images from Folder's filename into names to write each file name under its picture. Without it the pictures are numbered.
• Wire the original pictures into before for a before and after grid: each original sits above its result.
• columns 0 picks a near-square grid by itself. cell_size is the size of each picture, gap the space between them, and title writes a line across the top.

Good to know

• It works on a plain batch too, for example the 4 pictures of one KSampler.
• The cells take the shape of the pictures: wide pictures get wide cells, tall pictures tall ones, so there is no empty band around them. A mix of wide and tall gets square cells, and every picture keeps its shape.
• Very big grids are scaled down to 8192 pixels on the long side, and up to 1024 pictures are used.
• Do not put it after a gate that holds pictures back (Text Match's if_match): ComfyUI then skips the whole grid. Wire it to the pictures BEFORE the gate.
