Table images disappear in reports

My table contains a mol_image field of type Image (PNG). I can see the molecular image when I preview it, but when I export it to a report, only the first few rows are output correctly; the rest are missing. Currently, I can only use the Table to Image function and the Image View function to process a single row of data. How can I process a large number of rows? My Knime version number is 5.5.0.
