If they where not converted in anyway however or seemed not to be wargaming related they would not be suitable for the Dakka Gallery and thus removed.
If this was the case I'd advise you link such pics from Imgur, or if part of a blog thread to create conversions from for wargaming clearly mark them as such in the info in the Gallery.
Regardless, locking thread for now. If you have further queries regarding this please send a mail to the address above.
