Excuse' ? The built in image resizer in vB4 does work, settings for CMS and forum images are in different stylevars or you can modify the css yourself

.postbit .content img, .postbitlegacy .content img, .postbitdeleted .content img, .postbitignored .content img, .eventbit .content img {
	max-width: {vb:stylevar postbit_content_max_image_width};
	_width: expression(document.body.clientWidth > {vb:stylevar postbit_content_max_image_width.Size}? "{vb:stylevar postbit_content_max_image_width}": "auto" );
}

As far as signature images go simply copy the img size css definitions and apply that to the signature css class then any image in the signature also re-sizes if the image is larger than specified post image.

Mod is no longer needed unless BBR decides to update the mod to modify or overwrite these settings so you can still use lightbox etc.
