+
+## Why am I unable to load the TIFF file into Dynamic Web TWAIN?
+
+### Symptom
+
+When you attempt to import a TIFF file using Dynamic Web TWAIN, it will indicate that the file has been successfully loaded, but the image does not appear in the viewer.
+
+### Cause
+
+All versions prior to version 19.0 do not support importing 4-bit color images. If you encounter the issue mentioned above, your file may be using the deprecated JPEG compression standard.
+
+### Resolution
+
+Support for 4-bit TIFF format was added in version 19.1. Therefore, please update to version 19.1 to resolve this issue.
+
+> If the resolution doesn't work for you, please [contact us](https://www.dynamsoft.com/company/contact/).
