post image plugin and 2.5

Ok, I guess nobody has tried this yet. So I have given it a whirl.
I found the issue, in the post-image plugin around line 110 is this line

if( $use_thumb && ($img_url != $default_image) )
			$img_url = preg_replace('!(\.[^.]+)?$!', __('.thumbnail') . '$1', $img_url, 1);

I switched out the “.thumbnail” with “-150×150” and now the 150×150 thumbnail is displayed. I haven’t been able to alter it to display the medium thumbnail, since the medium size has not been consistent, it is dependent on the size of the image uploaded.
