Is the image compressed by the tool?

PNG is lossless, while JPG uses the quality slider you set, which you can balance against the file size.

How many photos can one long image hold?

Up to the per-run file limit. The canvas grows with each photo, so watch the final pixel height on very long sets.

Stack the gallery shots in reading order and export a single file to place under the product description.

Use the original-width option when your photos are already 750 or 1200 pixels wide, so nothing is resampled.

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