[Feature]: Accessibility - Missing Alt Text on Images

[Gupta-02]

Multiple tags across HTML files lack alt attributes or have empty alt="". This violates WCAG guidelines and harms users with screen readers. Examples include client images, owner image, and portfolio images.
Files Affected: index.html, portfolio.html, forum.html
Suggested Fix: Add descriptive alt text for all images. For decorative images, use alt="" or role="presentation".
