The original title is about implementing a dynamic OGP image generator for a blog using PHP GD, creating 1200×630 cards per post.

Short summary

DEV Community fixed bloated OGP (social media preview) cards showing identical sales banners by building a dynamic image generator in PHP GD. The system renders 1200×630 PNGs on-demand with disk caching, automatic font-switching for Japanese/Latin text, and visual continuity with their LP brand. Implementation uses ~375 lines of PHP in a single file.

• •All blog posts displayed same LP sales banner because no featured images were set
• •Built dynamic OGP generator in PHP GD: renders cached 1200×630 cards with post titles and multi-language font support
• •Minimal WordPress integration (~28 lines added): replaces featured image fallback with dynamic image URL
