Resize Feed Images

I am new to wordpressan hungryfeed and loking for a way to resize images from the ffeds to fit the area and make them responsize for my onovado theme:

Here is the current Code that i can see being Rendered:

<div class=”googlefont” style=”font-family:’Oswald’, serif !important; font-size:45px !important; margin: 0px 0px 0px 0px !important;”>
<p><center><span style=”color: #1d9dce;”>Technology News</span></center></div>
<style>
h3.hungryfeed_feed_title {}
img.hungryfeed_item {width: 100%;}
div.hungryfeed_feed_description {}
div.hungryfeed_feed_content {}
div.hungryfeed_items {}
div.hungryfeed_item {margin-bottom: 10px;}
div.hungryfeed_item_title {font-weight: bold;}
div.hungryfeed_item_description {}
div.hungryfeed_item_author {}
div.hungryfeed_item_date {}
</style>
<script type=”text/javascript”>
// Custom Javascript here…
</script>
<div class=”hungryfeed_items”>
<div class=”hungryfeed_item”>

I bolded what I tried adding “img.hungryfeed_item {width: 100%;}” and the area i am trying to affect in the feed formatting:

<div><div><img src=”http://www.wired.com/wp-content/uploads/2016/07/HonorHP-660×660.jpg&#8221; alt=”Review: Huawei Honor 5X”></div>Fewer bucks, more bangs. The post Review: Huawei Honor 5X appeared first on WIRED.</div>

<img class=”aligncenter” style=”width: 100%;” src=”http://sjutechnologygroup.com/wp-content/uploads/2015/07/divider.png&#8221; alt=”” />

Is there a way to change that code at rendering and replace it so that the image will stretch to just the full width and and then will resize with the page?
