This re-sizing using control +, – issue happens no matter what size the image is.
I ended up fixing this myself in the CSS code. The problem is the there is a background image behind my image that I need to get rid of.
It looks like the post thumbnail class has a background:
.post-thumbnail {
background: #b2b2b2 url(“images/pattern-light.svg”) repeat fixed 0 0;
display: block;
position: relative;
width: 100%;
z-index: 0;
}
So, if I edit the style.css file, I can set the background to none:
.post-thumbnail {
background: none;
display: block;
position: relative;
width: 100%;
z-index: 0;
}
This removed the background image and fixed the problem.
