1. Error: Failed to optimize image All return: error: "Failed to optimize image"

TL;DR

The most likely fix is to investigate and potentially revert or patch the changes introduced in OpenClaw version 2026.4.26 that affect the image tool's ability to optimize images.

Guidance

• Verify that the issue persists across different image formats and sizes to confirm it's not specific to certain types of images.
• Check the release notes or changelog for OpenClaw version 2026.4.26 to see if there are any known issues or changes related to the image tool or image optimization.
• Test the image tool with images sent via other channels (if possible) to determine if the issue is specific to webchat attachments.
• Consider downgrading to version 2026.4.23 temporarily to confirm if the issue is indeed caused by the upgrade.

Example

Notes

The issue seems to be specific to the image tool and the upgrade to OpenClaw version 2026.4.26. Other tools and functionalities appear to be working normally.

Recommendation

Apply workaround: Temporarily downgrade to version 2026.4.23 until a fix for the image tool issue in version 2026.4.26 is available, as this version is known to work correctly.
