Image helper class object creation

Hi,

Please try avoid sending same questions both to Kentico support and Devnet at the same time, it adds unnecessary processing from our part and 2 different people may be working on the same issue.

The file is indeed unfortunately not created when the MediaFileInfo.TYPEINFO.Events.After fires. The solution here is to create a custom InfoProvider for MediaFileInfoProvider and place your code there. I have tested following code:

[assembly: RegisterCustomProvider(typeof(CustomMediaFileInfoProvider))]
public class CustomMediaFileInfoProvider : MediaFileInfoProvider
{
    protected override void SetMediaFileInfoInternal(MediaFileInfo mediaFile, bool saveFileToDisk, int userId, bool ensureUniqueFileName)
    {
        // process file by system
        base.SetMediaFileInfoInternal(mediaFile, saveFileToDisk, userId, ensureUniqueFileName);

        // create thumbnails here, file exists on File system at this point
        todo
    }
}
