I have found    margin  0 auto  works for me  But I have also seen it NOT work due to the class being trumped by another specificity that had     float left  so watch for that you may need to add     float none  this worked in my case as I was coding a media query

Because your image is an inline-block element  You could change it to a block-level element like this    lt img src  queuedError jpg  style  margin auto  width 200px display block    gt    and it will be centered

i know this is an old post  but wanted to share how i solved the same problem    My image was inheriting a float left from a parent class  By setting float none I was able to make margin 0 auto and display  block work properly  Hope it may help someone in the future
