  "textContent": "I’m testing image rendering in a GPT Apps / MCP flow.\n\nIssue: an image hosted on DigitalOcean Spaces does not render when the markdown is returned directly from an MCP tool result.\n\nExample image URL:\n\n\n    https://bustet-name.server.digitaloceanspaces.com/2026/05/nameFile.jpg\n\n\nThe URL is public and valid:\n\n  * HTTP status: 200\n\n  * Content-Type: image/jpeg\n\n  * File size: about 104 KB\n\n\n\n\nThe MCP tool returns markdown like this:\n\n\n    ![Image](htps://busket-name.server.digitaloceanspaces.com/2026/05/nameFile.jpg)\n\n\nExpected behavior: the GPT Apps response should render the markdown image preview.\n\nActual behavior: when this markdown comes from the MCP tool response, the image is not displayed.\n\nImportant detail: if I ask ChatGPT directly to output the exact same markdown, using the same formatting instructions as in the tool description, the image renders correctly. So the problem seems specific to markdown/image rendering from MCP tool output in GPT Apps, not the URL itself.\n\nQuestion: is there a known limitation or required format for rendering external markdown images returned from MCP tools in GPT Apps?",
