Does the canvas width affect photo quality?

Photos wider than the canvas are downscaled to fit and narrower ones are scaled up, so start from the largest originals you have.

Can I keep every photo at its original size?

Choose the original-width option and each photo keeps its own pixel width, centred on the canvas.

Detail pages read better as one continuous image than as a gallery of mismatched sizes, and this lines every photo up on a shared canvas.

Set the separator height when you want a visible break between sections, or leave it at zero for one uninterrupted strip.

Stack product photos into one long detail image with a fixed canvas width.
