This extension makes it easy to generate descriptive alt-text for images. Simply provide an image URL, and the extension will make a call to the openai api to create a concise and descriptive alt text. This extension is Bring-Your-Own-Key (support for OpenAI only at the moment). If you don't have an API key yet, you can sign up for one at [OpenAI - Api Keys](https://platform.openai.com/api-keys).
