A lot of people are using wider displays and screen resolutions these days that are forced to stretch the original 600x600 stadium diagrams horizontally, rendering the baseball diamond into some kind of distorted rhombus. If you have this problem, I've widened the stadium diagrams from 600x600 to 1065x600 by expanding the margins around the original diagram. This will also create room around the diamond to accommodate the optional photographs that will be available with Version 11. You can get all 126 widened DMB parks here in a file called widerparks.zip, with yankee2009.jpg seen below:
those photos don't work out for you, you can always go back to the
originals, which I have available here in a file called originalparks.zip. These files are the same 600x600
dimensions as the originals but have been reduced in file size, and all
126 parks which used to measure 20.6 MB have been shrunk to 10.3 MB without losing image quality.
And, if you're using a wider display but want an alternate to the DMB diagrams, here are overhead shots from Google Earth of 28 of the 30 MLB parks, keeping the widened DMB diagrams for the two Florida parks (Miami was under construction at the time and Tampa Bay is, of course, indoors). They also measure 1065x600, and you can download the file googleparks.zip here, with AT&T Park seen below.
Hope these are of some use to people. Flag me down with any questions at my Yuku username @yahoo.com.
