右键先生-百度搜索 is a Chrome add-on developed by Browser Helper. It allows users to easily search for text and images on Baidu, one of the most popular search engines in China. Unlike other add-ons that offer a variety of features, this extension focuses solely on Baidu search, making it more suitable for frequent Baidu users.

With 右键先生-百度搜索, users can access Baidu search directly from the top-level context menu. In addition, it adds the option to search for selected text by right-clicking, as well as the ability to search for images by right-clicking on an image.

This extension is developed using Event Pages, which means it doesn't consume memory unless the search button is clicked. This ensures a better user experience without compromising system performance.

Please note that the image search feature is labeled as "experimental" and may not always work reliably. It relies on submitting the image URL to Baidu, so the image must be publicly accessible for the search to be successful. Additionally, Baidu image search does not support searching for data URI images (base64 format).

Overall, 右键先生-百度搜索 provides a convenient and efficient way for frequent Baidu users to access Baidu search directly from their right-click menu.
