The ImageEditor does not have its own logic for keeping the loaded images in the cache (unless its ImageStorageLocations=Cache property is not configured). If you are uploading the images following the approach from this live demo
, though, the uploaded image will be added to the application cache for 20 minutes:
sender, FileUploadedEventArgs e)
//Clear changes and remove uploaded image from Cache
(Stream stream = e.File.InputStream)
 imgData =
stream.Read(imgData, 0, imgData.Length);
MemoryStream ms =
ms.Write(imgData, 0, imgData.Length);
, DateTime.Now.AddMinutes(20), TimeSpan.Zero);
Please note that this is only a sample approach used for our demo application purposes and I would suggest that you review the following MSDN resources in order to consider how to integrate it best in the target by you scenario:
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
