Add the following to PropertyGroup:
```
<ImageMagickWebOutputPath>bin\ImageMagick</ImageMagickWebOutputPath>
```
Add the following to ItemGroup:
```
<FilesForPackagingFromProject Include="@(ImageMagickFiles)">
<DestinationRelativePath>$(ImageMagickWebOutputPath)\%(RecursiveDir)%(Filename)%(Extension)</DestinationRelativePath>
</FilesForPackagingFromProject>
```
This will ensure that all dependencies are copied to bin\ImageMagick on the webserver.
