Subtable Gallery ― kintone plug-in

Still hunting through tiny subtable thumbnails to find a field photo?

Drop photos or PDFs into the record details screen, and they instantly become gallery cards. Zoom in, add a note, delete what you don't need — all from the same screen.

Drag in two photos and the card count grows, then zoom in on one and close it — the whole flow in one take.

Tap a card to zoom in, then close it to return to the gallery.

Where it helps

On-site progress reports

Review yesterday's job-site photos on a single screen before the morning meeting. With scaffolding, wiring, and finishing work lined up side by side, there's no need to explain it verbally.

Inspection and pre-delivery records

Keep pre-shipment photos filed by part number. When an inquiry comes in, just open that record.

Comparing drawings with photos

Place a PDF drawing and photos of the actual item in the same row of cards, then zoom in to compare them.

How it works

Data is still stored in the subtable as before. Even if you remove the plug-in, the photos and notes stay in kintone.
Your business data is never sent externally. License verification only sends the kintone domain name and key.
It works entirely through official APIs and events, without touching kintone's internal structure.

SIGNPOST compliantHow it fits the SIGNPOST guidelines

Doesn't replace standard functionality (3-29, moderate UI customization). Designed around this principle: the subtable's storage structure is left untouched, only the display is changed to a gallery.
