Hey there - I've reviewed your changes - here's some feedback:

• Make sure the new Dom2Image library is added as a PackageReference in the server .csproj so that AddBootstrapBlazorDom2ImageService and IDom2ImageService resolve correctly.
• Add all missing localization keys (e.g. Dom2ImageTitle, Dom2ImageIntro, Dom2ImageNormalTitle, etc.) to your en-US.json and zh-CN.json so the new sample page texts load without errors.
• Consider unifying the component naming (Dom2Image vs Dom2Images) and extracting your CSS selectors (like "#table-9527") into constants to avoid magic strings and improve maintainability.
