Reproduce the visible problem
Open the page at the viewport size where the issue occurs. Capture the visible area for a layout defect, a selected area for a broken component, or the full page when position and surrounding content matter. Leave sticky-element hiding off if the bug involves a header, banner, or overlay.
Mark the symptom precisely
Crop to a useful amount of context and add an arrow, rectangle, or short note. For an overlapping label, show both the label and the element it covers. For missing content, include the surrounding section so the developer knows where to look. Review the capture for information you do not want to share.
Attach the evidence and reproduction steps
Save the screenshot as PNG or JPEG, then attach it to your issue tracker. Add the page URL, browser version, viewport size, steps to reproduce, and expected behavior in the report. Page to Image supplies the visual evidence; it does not automatically collect console logs, network requests, or reproduction steps.
