Image height and width

The plugin lets you slice images only by what you set in your WordPress theme, with this function:

So if you want images to be sliced to a certain size, just use the above function.

Does this make sense?

What I meant is that the plugin ignores wordpress media size settings, not theme settings, and it is not ok.
