A repeatable product photo batch: from originals to named files

One product, one batch

Choose a stable identifier such as MUG-042 before adding photos. Dama uses one shared filename prefix per batch, so separating products prevents unrelated images from receiving the same code. Keep your original folder unchanged.

Files receive sequence numbers in the order shown in the workspace. If order matters, add files in the desired order; operating-system file pickers may return their own ordering. Dama does not currently offer drag-to-reorder. Check and arrange image order inside the marketplace after uploading.

Make a small test export first

Add one landscape image, one portrait image and a detail photo. Choose dimensions, fit, background and format. A convenient default is a square canvas with Fit and a small margin, but review your destination rather than treating the preset as a requirement.

After Prepare images, compare the actual byte sizes, check crops and save a result. Open the downloaded copy to verify appearance. A successful export only means the browser created a file; it does not guarantee that a marketplace will accept it.

Naming rules you can predict

With prefix MUG-042 and first number 1, the first file becomes MUG-042-001.jpg when exported as JPG. Numbers are padded to at least three digits. Prefix characters outside letters A–Z, digits, hyphens and underscores are replaced with hyphens. Empty prefixes become product. The preview shows the final sanitized prefix, including adjustments for reserved filenames.

Each input keeps its assigned position during processing. If the second image fails, successful exports may be numbered 001 and 003. The gap is useful evidence of a failed file: review the error list and archive contents. Remove a failed file and prepare again if you need a continuous sequence.

Sequence numbers help organize files; they do not guarantee search rankings or storefront order. Never rely on filenames alone to select a listing’s primary photo.

Close the batch deliberately

1. Confirm that the number of prepared images matches the number you expect.
2. Download the ZIP or save individual successful images. ZIP is an archive, not extra image compression.
3. Extract the archive and inspect names, dimensions and appearance.
4. Upload to your platform and check the actual listing preview.
5. Save settings for next time. The prefix is saved too, so change the product code for a new item.
6. Clear the batch when finished. Clearing removes selected files and results from the workspace but leaves your controls and optional saved settings unchanged.

What comes back next visit

Saved settings belong to this browser profile on this device. They do not sync with another phone or computer, and clearing site data can remove them. Photos and ZIP files are not saved in a cloud library. Use “Forget saved settings” to delete the stored recipe without changing the controls currently on screen.
