Reseller Loop

All setups · Photos, Listing

We shot 40 items in a row and never sorted a single photo. Here's how

Photograph everything in one session, drop the photos in a folder, and an AI groups them by item, crops them and tells you which items are missing a front, back, tag or measurement shot.

The problem

Sorting photos into items is the most boring job in reselling, and it is where photos go missing.

The workflow

  1. Photograph items back to back in a consistent order: front, back, tag, details, measurements with a ruler.
  2. Save the whole session to one folder. No renaming, no albums.
  3. The agent looks at every photo in order and groups consecutive shots into items, using the size tag and garment as the signal for where one item ends.
  4. It flags neighbours that share a size tag (possible split item) and any item without a front view, back view, tag or measurement shot, so the seller checks those first.
  5. Each measurement photo is labelled (chest, length, sleeve, waist, inseam) before any number is read from it. This stops a bottom-width shot being read as a chest.
  6. Crops are made from the originals and the originals are never replaced.

What happened

Sorting went from an evening to a review of the flagged items only. The split-item warning catches the main failure, a snowsuit and a vest with the same size tag ending up as one item.

For your store

Our honest estimate from running this. Your store and numbers will differ.

What you need
Your phone camera and a fixed shooting order. Automatic grouping needs an AI that can read photos and someone who can run a script.
First try takes
Nothing to change how you shoot. About a week to get automatic grouping reliable.
First step tonight
At your next photo session, shoot every item in the same order: front, back, tag, details, then measurements with a ruler.
After a week
Faster sorting even without any AI, and you can see at a glance which items are missing a tag or measurement shot.
