Not possible to use it on 4.6

[mbajur]

Hello!

It seems it's not possible to use that gem on alchemy_cms 4.6. The thing is, branch alchemy-4 defines a following associaiton on Picture model:

https://github.com/AlchemyCMS/alchemy-dragonfly-s3/blob/alchemy-4/lib/alchemy/picture_monkey_patch.rb#L6

while there is no such model/table as Alchemy::PictureThumb on 4.6-stable branch of alchemy_cms, it looks like it was introduced in 5.x:

https://github.com/AlchemyCMS/alchemy_cms/tree/4.6-stable/app/models/alchemy

It all produces a following error when i'm trying to upload a picture:

ActiveRecord::StatementInvalid PG::UndefinedTable: ERROR:  relation "alchemy_picture_thumbs" does not exist
LINE 8:  WHERE a.attrelid = '"alchemy_picture_thumbs"'::regclass
                            ^
