Image Uploader can generate multiple thumbnails per one file sent to the server. To configure sizes of thumbnails and other parameters, you can manipulate a list of upload thumbnail settings. It can be done two ways:
UploadThumbnailNXXXparameters, where N is a number in range from 1 to 3.
UploadThumbnailXXXproperties to change specific settings.
First method is simpler, however it allows to upload not more than 3 thumbnails per one file. The second one does not have any limitation on the number of thumbnails.
To get an upload thumbnail on the server use the
HTTP POST field, where X is an index of the upload thumbnail.
The index of upload thumbnail list is one-based.
To configure other settings than fit mode and thumbnail dimensions, use appropriate
UploadThumbnailXXX property. E.g. to change the
JPEG quality, use the UploadThumbnailJpegQuality property.
If you choose to send resized thumbnails, you can specify the quality of resizing with the UploadThumbnailResizeQuality property.
You can also remove the upload thumbnail list element with the UploadThumbnailRemove() method.
