Hi @Robert Foster,
Thanks for posting your question in Q&A Forum.
I understand you're encountering an issue where uploading a banner image for a Teams Webinar causes white areas in the image to appear black. This behavior is commonly seen across various platforms and is often related to how images are rendered, particularly when:
- Non-standard color profiles (e.g., Adobe RGB or CMYK) are used
- PNG files contain transparency
- Layers are not properly flattened during image editing
To help prevent this color shift, I recommend trying the following adjustments:
- Flatten the Image: Ensure the background is solid white rather than transparent.
- Save as JPEG: JPEGs do not support transparency, which can help maintain consistent background colors.
- Use sRGB Color Profile: Save your image using the standard sRGB profile to ensure compatibility across platforms.
Please note that initial recommendations may not always resolve the issue immediately. However, with your input and any additional details you can provide, we’ll be better positioned to explore further solutions together.
I hope these suggestions prove helpful. Kindly give them a try and let me know how it goes. If the issue persists, I’ll be glad to continue working with you to find a resolution.
Thank you for your patience and understanding. If you have any questions or need further assistance, please don’t hesitate to reach out.
I look forward to your response.
