Image size problem

I am also having this problem. I loaded an image that is 600 x 337 px (and it shows correct dimensions in the media library), but when I choose that file for the Open Graph plugin Default Image setting, it automatically scales down to 300 x 169. When I upload a new image to the media library that is 400 x 337, your plugin automatically scales it down to 300 x 253.

So it appears that your plugin in will not allow a Default Image to have a maximum width or height greater than 300, and it scales the longest side down proportionately?

This is a problem for some social media networks that expect 16:9 images for their preview, or that display the og:image in a larger size. For instance, LinkedIn takes my 300×253 image (which the plugin scaled down from 400×337) and crops the top and bottom to achieve a 16:9 aspect ration AND it scales it up to 518 x 270 (which looks jaggy).

Is there a way to upload and select images for the Default Image that are larger than 300px in any dimension? Thanks.
