Wow, I guess reading is good. Who would have thought? I was just reading some older posts from the iThemes blog and noticed a post about making your WP galleries look great. Thought I would pass it along to the rest of you who missed it as well.
If you don’t want the square image thumbnails in your gallery, change is only a click away. Go into your dashboard and click Settings. Depending on whether you are using 2.5/2.6 or the new 2.7, you either need to go to the Miscellaneous or Media section, respectively. Once on that page, you need to uncheck the “Crop thumbnail to exact dimensions” checkbox. Unfortunately, this will only affect new images that you upload, since WP creates the various sizes of images when they are uploaded.
Hope this helps you guys!
