Sort Your Photos Before a Drop

3 min read · Updated June 2026

A drop posts in the order you upload your photos, so a little sorting first makes the whole thing go smoothly. Here’s how to get your photos lined up on a Mac or on Windows.

TL;DR
  • Keep each item’s photos together and in shooting order (all of item 1, then all of item 2 — not 1, 2, 1, 4 jumbled).
  • Sort your folder by date or name so you can select everything in order at once.
  • Upload PNGs or JPEGs, not HEICs.

Why order matters

Thryft Ship uses clustering to group your photos into items for you. Uploading them in shooting order — all of item 1 together, then all of item 2 — helps the clustering put items together correctly on the first try, and it runs faster too. If they’re jumbled (item 1, item 2, back to item 1), clustering has a harder time. The good news: if you shot each item’s photos one after another, they’re probably already in the right order by date.

You can always regroup items after they’ve been clustered — sorting first just makes that first pass more accurate, so there’s less to fix.

On a Mac (Finder)

  1. Open the folder of photos

    Find the folder in Finder and open it.

  2. Sort by date or name

    Switch to list view (View → as List), then click the Date Added or Name column heading so they line up in shooting order.

  3. Select all in order

    Click the first photo, then press Command + A to select them all (or hold Shift and click the last one). They’ll upload in that order.

On Windows (File Explorer)

  1. Open the folder of photos

    Find the folder in File Explorer and open it.

  2. Sort by date or name

    Switch to Details view (View → Details), then click the Date or Name column heading to put them in shooting order.

  3. Select all in order

    Click the first photo, then press Ctrl + A to select them all (or hold Shift and click the last one). They’ll upload in that order.

Use PNGs or JPEGs, not HEICs iPhone photos often save as HEIC files, which may not upload or display properly. Before a drop, set your iPhone to capture in a compatible format (Settings → Camera → Formats → Most Compatible), or convert your photos to JPEG or PNG first.

You can still fix the order later

Even after uploading, you can rearrange photos and change the posting order on the review screen before anything goes live — see How Captioning Works. Sorting first just makes it faster.

Common questions

Do all of one item’s photos need to be together?

Yes — keep each item’s photos in a row (all of item 1, then all of item 2) so they group into the right items.

Why shouldn’t I upload HEIC files?

HEIC (the default iPhone format) doesn’t always upload or display correctly. JPEG or PNG is safest.

What if I get the order wrong?

You can reorder photos and posts on the review screen before posting. See How Captioning Works.
