  1. Determine Your Thumbnail Style, Layout, and Display Text ===========================================================
  • Conceptualize the Thumbnail: Start by thinking about the text, style, and layout you want for your thumbnail. Decide how the text should be placed on the image and the style you want, whether it’s professional or cartoonish.

  • Specify the Image Style: Be clear about the style—whether you want a professional, cartoonish, or realistic look. This will guide the AI in creating the right type of thumbnail.
  • Include People (Optional): If your thumbnail features people, describe their positions, expressions, and appearance to make the thumbnail more engaging.
  1. How to Control Thumbnail Style Using LoRA Model (Optional) =============================================================

With the Flux Lora model, you can control various aspects of the image, like style and tone, to fit your needs.

  • Selecting the LoRA: Choose from different pre-trained LoRA models to adjust the style of your thumbnail, ranging from professional to vibrant, cartoonish looks.
  • Adjusting the Weights: Fine-tune the intensity of the LoRA’s effect by adjusting the weight parameter. Typically, weights between 0.5 and 0.8 work best for subtle control.
  • Mix and Match LoRAs: Combine multiple LoRAs to create more complex styles, adjusting weights for different parts of the image (e.g., background style, character features).
  1. Using Reference Photos for Personalization (Optional) ========================================================

For a personalized thumbnail, use the IP model to upload a reference photo. Make sure the reference expression matches the one you want in your thumbnail.

  • Enhance Creativity with Image Guides: You can set the “image guide” to 5 for more creativity, but this might result in less consistency in character features.

Important Tips: Write Effective Prompts for YouTube Thumbnail Generation

  • Keep the Prompt Length Moderate: Ensure your prompt is detailed but not overwhelming. A concise prompt is key to generating a thumbnail that captures your vision.
  • Place Key Elements at the Beginning: Mention the most important aspects, such as text, image style, or character details, early in the prompt.
  • Reference Photos: If you’re using a reference photo, be sure to describe the person and their characteristics in the prompt for more accurate results.
  • Refer to Examples, But Experiment: Use example prompts as guidance, but don’t hesitate to experiment. Creative prompts often yield unique thumbnails that stand out.

If you’re unsure about how to write prompts, try this free Prompt Generator Tool. For instance, input something like: “A YouTube thumbnail with the text ‘hello, try this with fluxailab’ on the left, and a woman pointing at the text on the right.”

Some Example:

prompt1: A vibrant, eye-catching YouTube thumbnail featuring a woman with an excited expression. Her eyes are wide with enthusiasm, her lips slightly parted in a smile, and her finger points directly to the left, drawing the viewer’s attention towards a large, bold text that reads “TRY THIS ON FLUX” in a bright, contrasting color. The background is a gradient of energetic colors that complements the overall mood, and the text is overlaid with a subtle, textured shadow for visual depth. The composition is dynamic, with the woman positioned slightly off-center to create visual interest.

prompt2: A young girl, with bright, curious eyes and a wide, excited smile, points her index finger to the right. Her expression is full of anticipation and wonder. The finger is pointing towards the right side of the frame, where a bold, eye-catching font proclaims “Try this on Flux.” The font is rendered in a modern, playful style, inviting viewers to explore the capabilities of Flux.
