Batch Image Resizer

I tried to resize 6 pcs of jpg files. Failed. OS: Windows 8.1 It can not resize jpg images unless you change the format jpg to bmp. It can not keep the image format while resizing. At this moment, it does not work. Easy to use though. Here is the error message for the writer of this program. Value cannot be null. Parameter name: format Details ----------------- See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.ArgumentNullException: Value cannot be null.

It does work and it is simple to use. I like the rename to number feature. The application has a major memory leak. Every time an image is processed the memory usage increases, after about 20 images the application crashes because of this. Please provide the sourcecode so I can at least fix this myself.

It simply does not work. An exe of 57 Kb??? it did not even install.
