Thai Text in Images

Gemini (Imagen) supports Thai text in generated images — one of the few AI image tools that does this well.

Include Thai text: "อร่อยทุกจาน สดใหม่ทุกวัน"
Warm lighting, food photography style, portrait format.

Limitations

• Free Gemini has daily generation limits (varies by usage)
• Complex text rendering may still have errors
• Very specific brand guidelines are hard to match exactly
• Cannot generate images of real people (policy restriction)
• Output resolution may not be print-quality

Key Takeaway

Gemini makes image generation accessible to everyone — no design skills needed. Be specific about style, colors, and composition. Iterate when the first result isn't right. And for Thai-language visuals, Gemini is currently the best free option.
