We want all the pictures published in black and white 有语法错误码
还是 We want all the pictures publishing in black and white
We want all the pictures published in black and white是对的,但是另有改：We want all the pictures to be published in black and white,主要区别如下,主要是意思上的区别.
We want all the pictures published in black and white.
我们想要（想买下）所有黑白印制的图片.
published in black and white做pictures的后置定语,可删去,
即,我们想要这些图（,是那些黑白的）
We want all the pictures to be published in black and white.
我们希望所有的图片都被印成黑白两色.
这句话的语法是want (sth./sb.) to ...,跟I want to eat是一个结构.
不过want后面有宾语pictures,所以不是主语we想、希望干什么,而是希望pictures怎么怎么样；
因为pictures和publish是动宾关系,因此要用被动,be published.
