Images belonging to FeedWordpress imports are resized - but where?

I'm using FeedWordpress to import news to the newsroll of a mother company from a subsidiary webpage.

The RSS-excerpt for a specific item can be seen here: Pastebin

As you can see, I'm getting the images I need into the RSS-file, into the start of the description block, as well as the content:encoded block:

<img width="2400" height="1350" src="http://ift.tt/1IquJ2Z" class="attachment-full wp-post-image" alt="Skogskullen 2 01 nyheter" />

FeedWordpress correctly parses the image and finds it. It's very weird though, because what gets imported is that same image, but resized with the "-150x150" flag. The original is nowhere to be seen.

I desperately need the import to work with the original image resolution. I've looked through the source for the plugins, but I can't for the life of me find any mention of 150x150.

I'm the sole developer of both sites, so I can work with both code bases. I'd appreciate any help or tips to what I can look at to figure this out.
