[Plugin: FeedWordPress] Automatically resize imported images

hello, i am loving this plugin, but am looking for a way to automatically resize the images server-side. i am currently doing it with CSS, but it negatively impacts the site’s performance. i’d like to be able to define a maximum width and a maximum height and have the image resized appropriately.

i have used imax width to accomplish this on other wordpress installs, but it doesn’t work with feedwordpress.

any help is much appreciated.
