Hello,

I don't know how to extend the default multiple upload feature, but you can disable it and replace it with a custom version of MFU: http://our.umbraco.org/projects/website-utilities/multiple-file-upload/bugs/20286-Support-for-custom-Media-Types

I've also done that in the DAMP Gallery.

Thank you for the feedback :)

There is a pretty simple workaroud for this, but you will have to do some coding :)

As much as I tried to change behaviour of mass uploader, nothing worked, so I decided to do some work right after upload.

In your Application handler constructor, add a handler for MediaService.Saved event like the following:

 public class ApplicationHandler : ApplicationEventHandler
{
public ApplicationHandler()
        {
            MediaService.Saved += new Core.Events.TypedEventHandler<IMediaService, Core.Events.SaveEventArgs<IMedia>>(MediaService_Saved);
        }
} 

        void MediaService_Saved(IMediaService sender, Core.Events.SaveEventArgs<IMedia> e)
        {
            foreach (IMedia mediaItem in e.SavedEntities)
            {
                if (mediaItem.ContentType.Alias.Equals("Image", StringComparison.InvariantCultureIgnoreCase) && mediaItem.Parent() != null && !mediaItem.Parent().ContentType.Alias.Equals("Folder", StringComparison.InvariantCultureIgnoreCase))
                {
                    var firstCustomType = mediaItem.Parent().ContentType.AllowedContentTypes.Where(t => !t.Alias.Equals("Image", StringComparison.InvariantCultureIgnoreCase)).FirstOrDefault();
                    if (firstCustomType != null)
                    {
                        IMediaType newType = ApplicationContext.Current.Services.ContentTypeService.GetMediaType(firstCustomType.Alias);
                        if (mediaItem.ContentTypeId != newType.Id)
                        {
                            mediaItem.ChangeContentType(newType, true);
                            ApplicationContext.Current.Services.MediaService.Save(mediaItem, 0, false);
                        }
                    }
                }
            }
        }

Your folder where you want to upload custom images needs to allow both images and custom image types. This way uploader will not block images to upload and this code will do the magic after upload.

Basically it changes normal image type to custom image type. Limitation is that this works only if you need one custom image type because it takes first one which is not Image. If you need to support multiple custom types for mass upload you will have to do saom small rework of this code.

Please let me know if this works for you.

@ Dejan you're a legend

Code worked exactly as is, I'm creating different media image types with different crops, this works amazingly well

Works like a miracle! Thanx!
