Exclude folder from ImageProcessor
Hi,

I have a folder "~/Resources/Images" where i put in all image that are used for the site to work, like loader gifs and icons.

I also wanted to add favicon png's to this folder and added versioning to these files to prevent the caching of new versions:
```
<link rel="icon" type="image/png" sizes="16x16" href="/Resources/Images/Favicon/favicon-16x16.png?version=1">
<link rel="icon" type="image/png" sizes="32x32" href="/Resources/Images/Favicon/favicon-32x32.png?version=1">
<link rel="icon" type="image/png" sizes="48x48" href="/Resources/Images/Favicon/favicon-48x48.png?version=1">
```
I found out that the questionmark in the url in combination with these parameters raises an error for imageprocessor. By intercepting the ValidatingRequest event, i found out that all images files, with or without a questionmark in the url, are being processed by ImageProcessor.

What i want, also for performance reasons, is to exclude the complete "Resources" folder from being processed by ImageProcessor. Is the a way or a setting to achieve this? Or is it possible to let ImageProcessor only process files in the "~/Media" folder? I couldn't find it in the imageprocessor documentation. In the imageprocressor "processing.config" file the setting "interceptAllRequests" is set to false but still all images are getting processed at the moment.

Bestregards,

iNETZO

I have the same issue. Getting hundreds of exceptions such as the below:

ImageProcessor.Common.Exceptions.ImageProcessingException: ProcessImageAsync 610 : No image exists at https://<container>.blob.core.windows.net/media-prod/favicon-32x32.png

Can anyone provide any information about how to exclude certain files or folders from image processor?

For info, the site is hosted on Azure with a single web app and using Azure blob storage for the media. The security config is as follows:

<?xml version="1.0" encoding="utf-8"?>
<security>
  <services>
    <!--<service name="LocalFileImageService" type="ImageProcessor.Web.Services.LocalFileImageService, ImageProcessor.Web" />-->
    <!--Disable the LocalFileImageService and enable this one when using virtual paths. -->
    <service name="CloudImageService" type="ImageProcessor.Web.Services.CloudImageService, ImageProcessor.Web">
      <settings>
        <setting key="Container" value="media-prod"/>
        <setting key="MaxBytes" value="8194304"/>
        <setting key="Timeout" value="30000"/>
        <setting key="Host" value="https://<container>.blob.core.windows.net/"/>
      </settings>
    </service>
    <service prefix="remote.axd" name="RemoteImageService" type="ImageProcessor.Web.Services.RemoteImageService, ImageProcessor.Web">
      <settings>
        <setting key="MaxBytes" value="4194304" />
        <setting key="Timeout" value="3000" />
        <setting key="Protocol" value="http" />
      </settings>
      <whitelist>
        <URLs including the site domain where the issue is occurring and the blob storage container domain (both https)>
      </whitelist>
    </service>
  </services>
</security>
