Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/no-img-without-dimensions. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

<img src="/report.png" alt="Report" />

Corrected pattern

<img
  src="/report.png"
  alt="Report"
  width={1200}
  height={800}
/>

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/no-img-without-dimensions diagnostic in the current repository. Required change: - Add width and height attributes, or reserve the image's aspect ratio with an explicit CSS box before it loads.

Reference transformation:Before:

<img src="/report.png" alt="Report" />

After:

<img
  src="/report.png"
  alt="Report"
  width={1200}
  height={800}
/>

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Preserve resource ownership and cleanup. Do not move work into a hotter render or frame path. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.

More Performance rules from the rules reference:

react-doctor/no-inline-bounce-easing: Use `cubic-bezier(0.16, 1, 0.3, 1)` (ease-out-expo) for natural deceleration — objects in the real world don't bounce
react-doctor/no-inline-prop-on-memo-component: Hoist the inline `() => ...` / `[]` / `{}` to a stable reference (useMemo, useCallback, or module scope) so the memoized child doesn't re-render every parent render
react-doctor/no-json-parse-stringify-clone: JSON parse/stringify deep clone
react-doctor/no-large-animated-blur: Keep blur radius under 10px, or apply blur to a smaller element. Large blurs multiply GPU memory usage with layer size
react-doctor/no-layout-property-animation: Use `transform: translateX()` or `scale()` instead — they run on the compositor and skip layout/paint
