+// #TINY-11842
+
+In previous versions of the **Image Optimizer** premium plugin, dragging and dropping supported image files onto the placeholder could fail due to inconsistent file type detection. The issue occurred because only the MIME type or the file extension was checked, resulting in discrepancies when handling certain image files.
+
+{productname} {release-version} resolves this issue by updating file type detection to consider both the MIME type and the file extension when verifying supported formats. This enhancement ensures more reliable and consistent behavior when dragging and dropping image files.
