Photos should show the full equipment
A buyer needs to see the complete machine, not only a close-up or a decorative image.
Show manufacturing and delivery
Factory production, testing, packing, loading, and customer-site photos help the buyer understand delivery capability.
Match captions to facts
Captions should describe what the photo actually shows: RO host, pretreatment tanks, control cabinet, packaging, or project site.
Use photos to start a real conversation
When a buyer sees similar equipment and asks about their own water source, the inquiry becomes more concrete.
