Turn a Photo Series into One Tall, Shareable Image

A long image can tell a story from top to bottom, collect several related photos in one shareable file, or present a sequence that is easier to follow than separate uploads. Good results come from planning the order, keeping the images visually compatible, and checking how the full composition reads after export.

1. Decide how the long image will be used

Choose the destination before arranging your photos. A social post, message, or webpage may have different limits for width, file size, or display length. If you are combining screenshots, keep text at a readable scale; if you are making a travel sequence, think about how one scene should lead into the next.

2. Prepare the photos and their order

Select images with a shared subject or a clear progression. Put them in the order viewers should follow, and remove near-duplicates that slow the story down. Similar lighting and crop sizes help the combined image feel cohesive, while too many unrelated panels can make it harder to scan.

3. Assemble the sequence

Open Knockout’s Long Collage tool and add the photos in the intended order. Use the available layout controls to arrange the panels into one continuous composition. For screenshots or pages with fine text, check that neighboring images use a consistent scale before combining them.

4. Review every transition

Scroll from the top to the bottom of the preview. Look for sudden changes in brightness, repeated content, awkward crops, and joins that interrupt a line or a subject. Adjust the order or framing where needed, then review the complete image again rather than only its individual panels.

5. Export and check the full file

Save a copy that fits the destination’s size and format requirements. Reopen the exported file and inspect both the overall sequence and the smaller details. Keep the source photos so you can change the order or create a shorter version later.

Long-image checklist

• The order is clear from beginning to end.
• Panel sizes, colors, and crops work together.
• Important details remain readable at the intended display size.
• The exported file matches the destination requirements.
