Reaction thumbnail with graphic elements
A surprised face expression with wide eyes and open mouth, bold red arrow pointing upward in the corner, bright yellow and red color scheme, high contrast, dramatic lighting, clean background

Before-and-after split comparison

Visual contrast between two states immediately communicates transformation and value.
Product showcase with dramatic lighting
A tech gadget centered on a dark surface with dramatic spotlight from above, glowing screen, reflective surface, moody blue and purple lighting, clean minimal composition

Text-focused announcement thumbnail
A bold announcement card with large text space in the center, vibrant gradient background from orange to pink, geometric accent shapes in corners, modern clean design
Leaves clear space for title text overlay while creating visual energy with gradients and shapes.
Action scene with motion
A person mid-jump with motion blur, dynamic diagonal composition, bright outdoor lighting, blue sky background, energetic pose, sense of movement and excitement

Limitations to know before generating
- Text rendering inside generated thumbnails may not be accurate or readable; plan to add text overlays in a separate editing step.
- Results require review for composition and readability at small sizes before publishing.
- Generated faces and expressions may vary; multiple generations may be needed to achieve the exact emotion you want.
- Platform-specific size requirements must be handled by choosing the correct aspect ratio setting before generation.
