TEETH / SLIDER / TRACK
Image Guide
Best search: zipper close up / zipper teeth macro / metal zipper close up / zipper slider close up / zipper track detail / black zipper macro / open zipper close up. Backup: fastener close up / metal teeth pattern / fabric hardware detail / metal slider detail / textile edge hardware / zip seam close up. Avoid: zipper repair / how to fix zipper / sewing tutorial / clothing size guide / brand-logo product shots / jacket shopping.

Visual principle
Treat the zipper as a linear hardware system: teeth, slider, opening, fabric edge, and repetition rather than clothing instruction or product buying.
What to notice
Look at tooth spacing, metal finish, slider geometry, the split between open and closed tracks, stitching, and the contrast between hard hardware and soft textile.
Editorial use
Use narrow vertical crops for long tracks, macro details for teeth and sliders, and one wider textile image to keep the archive from becoming overly mechanical.
