 |Lists|Function:<br>`run.log_list(name, value, description='')`<br><br>Example:<br>run.log_list("accuracies", [0.6, 0.7, 0.87]) | Log a list of values to the run with the given name.|
 |Row|Function:<br>`run.log_row(name, description=None, **kwargs)`<br>Example:<br>run.log_row("Y over X", x=1, y=0.4) | Using *log_row* creates a metric with multiple columns as described in kwargs. Each named parameter generates a column with the value specified.  *log_row* can be called once to log an arbitrary tuple, or multiple times in a loop to generate a complete table.|

-|Images|Function:<br>`run.log_image(name, path=None, plot=None)`<br><br>Example:<br>`run.log_image("ROC", plot=plt)` | Log an image to the run record. Use log_image to log an image file or a matplotlib plot to the run.  These images will be visible and comparable in the run record.|
+|Images|Function:<br>`run.log_image(name, path=None, plot=None)`<br><br>Example:<br>`run.log_image("ROC", plot=plt)` | Log an image to the run record. Use log_image to log a .PNG image file or a matplotlib plot to the run.  These images will be visible and comparable in the run record.|
 |Tag a run|Function:<br>`run.tag(key, value=None)`<br><br>Example:<br>run.tag("selected", "yes") | Tag the run with a string key and optional string value.|
 |Upload file or directory|Function:<br>`run.upload_file(name, path_or_stream)`<br> <br> Example:<br>run.upload_file("best_model.pkl", "./model.pkl") | Upload a file to the run record. Runs automatically capture file in the specified output directory, which defaults to "./outputs" for most run types.  Use upload_file only when additional files need to be uploaded or an output directory is not specified. We suggest adding `outputs` to the name so that it gets uploaded to the outputs directory. You can list all of the files that are associated with this run record by called `run.get_file_names()`|
