I assume you're using DotNetNuke 6.2+

If so, the DNN core has an image utility inbuilt to it.

In DotNetNuke.Common.Utilities.ImageUtils, there is a method with a signature of:

public static string CreateImage(string sFile, int intHeight, int intWidth)

So, you should be able to just call:

ImageUtils.CreateImage(myPath, 500, 500)

To resize a file to 500 width + 500 height.

A few things to try:

1.) post the full code for your codebehind.

2.) try a different image
