disable auto rotation

Hi all,
I don't want to enable auto rotation and therefore I have iu.addParam("AllowAutoRotate", "false"); in configuration. It's also default behaviour.

But it doesn't work:
- I have photo with domension 1944 x 2592 and EXIF orientation is "left bottom"
- I see this photo in ImageUploader component "left bottom" oriented and not in original orientation
- thumbnails aren't created and posted to the server in this case

Here is my configuration:
iu.activeXControlEnabled = true;
iu.javaAppletEnabled = true;
iu.activeXControlVersion = "4,7,16,0";
iu.javaAppletVersion = "2.7.16.0";
iu.javaAppletCached = true;
iu.activeXControlCodeBase = "includes/ImageUploader4.cab";
iu.javaAppletCodeBase="includes/";

//component configuration
iu.addParam("Action", "addDocument.htm"); //must be
iu.addParam("AutoRecoverTimeOut", "3000");
iu.addParam("AllowAutoRotate", "false");
iu.addParam("AllowRotate", "true");
iu.addParam("ShowDescriptions", "false");
iu.addParam("MaxFileCount", "20");
iu.addParam("MaxFileSize", "51200000"); //=50MB
iu.addParam("MaxTotalFileSize", "102400000"); //=100MB
iu.addParam("ExtractExif", "ExifDateTime;ExifDateTimeOriginal;");
iu.addParam("FolderPaneSortMode", "Name");

//component apperiance
iu.addParam("BackgroundColor", "#e8d5c4");
iu.addParam("TreePaneWidth", "210");
iu.addParam("FolderPaneHeight", "200");
iu.addParam("PreviewThumbnailSize", "70"); //96 default
iu.addParam("AutoRecoverMaxTriesCount", "1");
