The size constraints on those images are specified in the CB configuration manager in the "Images" tab. There you specify the maximum size you wish to allow members to upload and also what size you want the generated thumbnails to be. CB checks these against what's actually uploaded by the user and does not resize the uploaded image, but instead rejects it. Whether these are too big or not is kind of dictated by the template you are using.
In earlier versions of CB, I saw the thumbnail get generated anyway in such cases and it was only partially rendered.
