Product Image Guidelines

Purpose

Product images help users identify ammunition products while browsing, scanning, or importing catalog records.

Images are optional. RoundCount must continue working when an image is missing or unavailable.

Supported Formats

Preferred:

  • WebP

Accepted:

  • JPEG
  • PNG

Not accepted:

  • GIF
  • SVG
  • TIFF
  • BMP
  • Renamed or executable files

File Naming

Store images using:

images/<manufacturer>/<product-identifier>.<extension>

Use the UPC as the filename when available:

images/winchester/020892201989.webp

When no UPC exists, use a normalized manufacturer SKU:

images/lake-city/lc-m193-55gr.webp

Naming requirements:

  • Lowercase manufacturer directories
  • Lowercase filenames
  • Hyphens instead of spaces
  • Letters, numbers, hyphens, and periods only

Image Size

Recommended dimensions:

800 x 800 pixels

Maximum dimensions:

1600 x 1600 pixels

Recommended maximum size:

500 KB

Absolute maximum size:

1 MB

Images should be resized and compressed before being committed.

Image Content

Preferred images should:

  • Clearly show the product packaging
  • Have a plain or uncluttered background
  • Be properly oriented
  • Be sharp and well lit
  • Show identifying product information when possible

Do not include:

  • Personal information
  • People
  • Receipts
  • Shipping labels
  • Storage locations
  • Personal inventory markings
  • Unrelated objects
  • Contributor-added watermarks

Catalog Record Reference

Catalog records should contain a repository-relative path:

"image": {
  "path": "images/federal/029465063924.webp",
  "sha256": null
}

Do not place the complete Gitea URL in each product record.

RoundCount should construct the download URL from its configured catalog repository address.

SHA-256 Checksums

Generate a checksum with:

sha256sum images/federal/029465063924.webp

The resulting 64-character value may be stored in the product record.

Checksums allow RoundCount to verify that the downloaded image is complete and unchanged.

Missing Images

When no product image is available, use:

"image": null

RoundCount should display its built-in placeholder image.

Do not store separate copies of the placeholder for every product.

Image Validation

The catalog validation tool should eventually verify:

  • The referenced image exists
  • The extension is supported
  • The file is a valid image
  • Dimensions are within limits
  • File size is within limits
  • SHA-256 matches when provided
  • The path remains inside the images directory

Only add images that may legally be stored and redistributed.

Preferred sources:

  1. Original contributor photograph
  2. Manufacturer-provided media
  3. Distributor media with redistribution permission
  4. Properly licensed third-party media

Image source information should be documented when appropriate.
