Reproducing Steps:
1. Right Click on any image and Select the resize option from the drop down
2. Select Custom radio button in the resize window
3. Enter the negative values in either or both of the fields.
4. Click on resize button
5. Verify the image which is been resized.
6. The resized image is displayed as inverted image(BUG).
Suggestion: Whilst inserting the negative integer into the custom fields the resizer software must throw an exception saying that "User cannot enter the negative integers."
Comments: ** Comment from web user: BriceLambson **
The fields definitely need to be validated (See [Work Item 08347](http://imageresizer.codeplex.com/workitem/8347). However, I believe that the only valid reason a user would enter a negative number is because they intend to flip the image on that axis. Already, if a user leaves a field blank, Image Resizer calculates what the value should be based on the other value they entered.
If I do decide to keep the inverting behavior, I will certainly document it.
