How-to Guide

Create an Image Grid for Bug Reports

The #1 complaint from developers: 'I can't reproduce it.' A screenshot grid showing expected state → trigger action → broken result eliminates back-and-forth and gets bugs fixed faster.

Try MergeFrame (Free)

Bug report quality directly correlates with fix speed. A grid with expected state, trigger action, and broken result gets picked up in hours, not weeks.

The 3-step grid: cell 1 = expected behavior, cell 2 = the trigger action, cell 3 = the unexpected result. Number each cell. For complex bugs, use 2×3 (6 steps). For responsive bugs, 2×2: desktop correct/broken + mobile correct/broken.

Add arrows or circles highlighting the buggy element before merging. It tells the reader where to look, which is the part of a bug report that most often goes missing.

How to Do It: Step by Step

1
Capture the 3 key states
Expected state → Trigger action → Broken result. Same zoom, same window size.
2
Annotate if needed
Add arrows or circles highlighting the buggy element before importing.
3
Open MergeFrame
Go to mergeframe.com: free, no login, works on all OS.
4
Select a Strip of 3 layout
Left to right = expected → action → broken. Chronological and universal.
5
Attach to your bug ticket
Export PNG, attach to GitHub, Jira, Linear, or Slack.
