Fixes #1121
Several blog posts and documentation pages included images without descriptive alt attributes. Updated them to be descriptive and meaningful for better accessibility and SEO. This ensures compliance with WCAG guidelines and improves the user experience for screen readers and search engines.
Why it matters: Accessibility and SEO.
Acceptance criteria:
Identify images in blog/ or docs/ with empty/placeholder alt text
Update the markdown to include descriptive alt="..." attributes
Include a short explanation of why the chosen text is descriptive in PR
Type of Change
Bug fix (non-breaking change that fixes an issue)
New feature (e.g., new page, component, or functionality)
UI/UX improvement (design, layout, or styling updates)
Performance optimization (e.g., code splitting, caching)
Documentation update (README, contribution guidelines, etc.)
Other (please specify): Accessibility improvement
Changes Made
Blog Posts (8 files updated):
index.md: Changed generic "UI-UX Design impact in future" to "Infographic showing career growth and opportunities in UI/UX design"
index.md: Updated to "Illustration of human qualities that AI cannot replace in UX design"
index.md: Replaced "img1" with "Flowchart illustrating the user research process in UX design"
index.md: Corrected to "Promotional banner for GitHub Copilot Coding Agent feedback rewards"
Other blog files maintained their already descriptive alt text
Documentation (14 files updated):
setup-environment.md: Updated 6 images from "GitHub" to specific Git installation screenshots
docs/sql/SQL-joins/.md: Changed "GitHub" to descriptive SQL join diagram/animation descriptions
docs/Google-Student-Ambassador/.mdx: Replaced "GitHub" with detailed program-related image descriptions
docs/sql/SQL-Advance/*.md: Updated to specific database concept illustrations
Why the chosen alt text is descriptive:
Each updated alt attribute now provides a clear, specific description of the image's content and purpose, rather than generic placeholders. This ensures:
Accessibility: Screen readers can convey meaningful information to visually impaired users
SEO: Search engines can better index and understand page content
User Experience: Users with slow connections or disabled images get context about what's missing
Dependencies
No new dependencies required
No version updates needed
