To map your CSV columns (including image URLs) when uploading a dataset in Phoenix Prompt Playground, use the "Create via CSV" option in the Datasets tab. After uploading, you should see a step to map each CSV column to its role (e.g., set your image URL column as the image variable, your text as the prompt, etc.). If you do not see this mapping step, it may be a UI issue or a limitation in your current version鈥攃olumn mapping is expected as per the official documentation (<https://arize.com/docs/ax/prompts/prompt-playground/image-inputs-in-playground#method-1-csv-upload|see here>).
If the mapping UI does not appear, try re-uploading the CSV or updating Phoenix to the latest version. Supported image columns should be mapped as image variables, and you can reference them in your prompt using `{{variable_name}}`. If the problem persists, it may be a bug or a missing feature in your deployment (<https://arize.com/docs/ax/prompts/prompt-playground/image-inputs-in-playground#method-1-csv-upload|source>).
