I like the 200x200 setting that outputs the 200x115 for this particular site. First time I've ever used the plugin, but I like it.
I figured if I put 200x100, it'd display either A) a cropped version or B) a non-square version that fits within a 100x200 area, depending on the image's dimensions.
Apparently some 200x200 "hack" or a variation will get the job done. It's just not intuitive.
Anyways, last thing I'll request on this plugin is that it enables "Excerpts" for Pages. So if this plugin is activated, Pages have Excerpt box. Or, even better, an option within the plugin's settings to turn Page Excerpts on or off.
I tried a 2 other plugins like this one and apparently 1 or 2 of the 3 (i.e. not this one) enabled it and then it went away when I settled on this plugin. I thought it to be an appropriate and convenient feature.
Thank you again for this plugin.
