+### Changed
+
+- Images will not be added to spreadsheet if they cannot be validated as images.
+
 ### Deprecated
 
 - Php8.4 will deprecate the escape parameter of fgetcsv. Csv Reader is affected by this; code is changed to be unaffected, but this will mean a breaking change is coming with Php9. Any code which uses the default escape value of backslash will fail in Php9. It is recommended to explicitly set the escape value to null string before then.
