Inserting a modified image

Hi there,

I want specific size of images for my blog articles – so want the editors to be able to upload an image, crop it, resize it (if required) and insert that into the post.

However, even I can’t work out how to do it.

So the steps I am following…

1) Click upload/insert in the article.
2) Select the image.
3) Click edit image.
4) Use scale image and image crop as required.
5) Then… what?

1) Save button doesn’t do anything.
2) If I select insert into post it does it at full size, not the new cropped dimensions.
3) If I click save all changes there’s no insertion, just a list of images – and they don’t reflect my new image. If I insert one of them, it creates a link to an image whereas I thought I was just inserting an image?

Any help on this would be appreciated!
