Hi,

I have setup Umbraco 7.2.1 to save Media items to Azure blob storage.

If using a external source (Azure) for images the image crop/re-size functionality does not work.

Do overcome that I have added ImageProcessor.Web.Config and set the ImageProccessor security.config file:

<security allowRemoteDownloads="true" timeout="300000" 
maxBytes="4194304" remotePrefix="/remote.axd">
 <whiteList>
  <add url="http://[herecomesblobname].blob.core.windows.net" />
 </whiteList>
</security>

So if in the website I want to get a crop/re-size image I prefix the URL with "/remote.axd?"

For example:

/remote.axd?http://[herecomesblobname].blob.core.windows.net/media/357/image.jpg?center=0.30711610486891383,0.4625&mode=crop&width=360&height=360&rnd=130702162430000000

I need to do the same for the thumbnails in Umbraco 7.2.1 Backoffice.

For example: How can I add prefix "/remote.axd?" for the thumbnails urls in the Folder Browser in the Media section?

Because if displaying more than 5 full-sized images instead of thumbnails, the Folder Browser is very slow and freezes.

I am talking about the images here:

If using Azure storage for images, thumbnails are not generated and preview images are loaded in full size instead. This is a huge performance issue for me as the original images are large. So please, how can I prefix the thumbnails urls with "/remote.axd?" in Backoffice?
