ASP.net (C #) bulk upload

Upload pictures for this site needs, refer to a lot of mature experience in the ASP.net platform using C # language, to do this automatically bulk upload images. ASPX file, and by the debugged, the use of this site, are sent to for your reference, I hope more master pointers.
The program main features are:

(1) can upload their own need to change the directory to the server, upload the source image, thumbnails, text watermark, image watermark charts to map and set the directory into the different directories;

(2) automatically checks the directory, such as nothing to the selected directory, will automatically create them;

(3) the size of thumbnails generated its own set;

(4) can choose whether to need to generate a text watermark, image watermark, watermark map not generated by default;

(5) can add, delete needed to upload pictures.

In this process the relevant comments were added, so issue a code, no explanation.
