Epub Images will not fit on Nook screen

Hello,

I converted a pdf through ABBYY Fine reader to epub. The problem that I have is that all the images are too big to fit on the screen of my Nook Simple touch.

I tried converting from EPUB to EPUB through Calibre to see if this would fix the problem but the problem carried through.


I tried many things to get the images to fit on the screen but none of them have worked so far. Among these I re-sized the images in the epub file to be smaller than the screen width but still they kept showing up oversized to the screen.
I am not very familiar with HTML Code so maybe there is something there that I'm overlooking, hopefully somebody can help me figure this out.

Here's the code for a image in my epub file, maybe somebody can spot what's keeping the images from fitting on the Nook's screen:


<p>...</p>
<div>
<div>
<img src= “main-13.png" alt style= “width: 399pt; height: 582pt; -webkit-column-break-inside: avoid; max-width: 466px; -webkit
column-break-before: always; max-height: 640px; display: block; calibre_f3fa75ca98eb4413a4ee413f20160226= “12”>
</div>
</div>
