If the image doesn't conform to the proportions of those sizes, you end up with a distorted image - in fact, both the thumbnail and the enlarged images are distorted in the test example - see attachment.

As explained in my first post here "The size/resize dimensions can easily be altered to suit your individual requirements. Just change the width= and height= dimensions in the code below."
I've used this BBCode to display large local images of fixed proportions. Ideally there might be {option}s included for proportions however that is beyond the abilities of this learner driver I'm sorry. I'd be happy for anyone with the skills to improve the dimension constraints.

If you've made edits to your postbit.css as explained in this thread then you will have signature interference with image or table align="left or right". It's covered in post#12 above. If you check out my demo (second post in that thread) you'll see that this BBCode doesn't force the signature to wrap around the image and text unless you've made those postbit.css edits.
Also, the Preview Post will show the signature wrapping around the image and text, however when posted, it should display properly.
