Container photo downscale & ZIP

Each image is downscaled to fit 1280×760 (landscape) or 760×1280 (portrait), converted to JPEG, and renamed sequentially. Location EXIF is removed in the re-encode.

Up to 50 images · 20 MB max per file · nothing kept after download.

A modern phone camera produces 4–12 MB per photo. A routine six-photo condition set therefore lands at 25–70 MB — over the attachment cap of most corporate mail servers, and slow to move over the patchy connectivity typical of container yards and inland depots. Downscaled to 1280 px JPEG, the same set is usually under 2 MB and still shows dents, gasket damage, and door-seal condition clearly enough for repair estimates and dispute reviews.

Renaming matters as much as size. Photos arriving as IMG_4021.jpg force the recipient to open each file and guess which unit it belongs to. Named by container number (MSKU1234565-01.jpg, -02, …), the same photos can be filed, forwarded, or imported into a depot system without any manual matching.

Privacy: images are processed in server memory for the duration of the request only — nothing is written to disk or retained after the ZIP downloads. The re-encode also strips GPS location metadata, so a photo taken at a private address does not carry those coordinates to a third party.

ZIP vs. individual files: one attachment survives mail-gateway limits on attachment count, keeps the photo order intact, and downloads as a single click for the clerk on the receiving end. Send files individually only when the recipient's system ingests attachments one by one — or skip the manual step entirely with the Checker email dropbox, which auto-files inbound photos by container number.
