Duplicate images in the gallery? How to find duplicates before handover
Uploaded twice, merged from two cards, accidentally imported twice: duplicates bloat galleries and confuse clients. How to find them before the client does.
It happens faster than you’d think: you upload a gallery, the upload breaks off, you start again — and suddenly some images are in there twice. Or you merge two memory cards that overlap. The result is a bloated gallery in which the client rates the same image twice.

Why duplicates do more harm than you’d think
Duplicate images aren’t just untidy. They cost unnecessary storage, distort the image count you advertise with (“800 shots!”), and they confuse the client during selection: did they already mark this image, or is this the second copy? In the worst case they pick both, and you end up editing the same shot twice.
How duplicates creep in
The most common sources are aborted and restarted uploads, merging several cards or imports, and images that exist as both JPEG and RAW and then both end up in the gallery. Searching manually is still doable with a hundred images; with several hundred it’s practically hopeless.
Check before publishing
The right moment for the duplicate search is before you put the gallery live. An automatic comparison finds identical or near-identical files and proposes them for removal. It takes seconds and spares you the embarrassing situation of the client noticing the duplication first.
Make it a routine: upload, check duplicates, then release. That one minute pays off in a clean, professional-looking gallery.
Conclusion
Duplicates are a small but visible quality problem. They waste storage, distort numbers and confuse the selection. A quick duplicate check before going live belongs in every clean gallery workflow.
Lumio is built exactly for that: before publishing, you find duplicate images in the gallery with one click and remove them before the client even gets to see them.
