I think is what I've been looking for, but I'm confused.

WordPress has a feature called post-thumbnails.

When you try to display a picture that you have uploaded to wordpress, generally your theme will use a feature called post-thumbnails. This feature resizes your image into the appropriate dimensions needed for your theme. Sometimes, wordpress’ resizing crops either the sides or the bottom depending on how the post-thumbnail is defined (it always crops to the middle). This plugin specifically sets the crop at any size for any given image.

Hope that helps.

@sewpafly, so in other words…I can decide what part of the image is cut off? What if I do not want any part of the image cut off?

Good luck trying to do that with stock wordpress :), but yes you can do that with this plugin.

FYI, some post-thumbnails set the “crop” attribute which means that the image needs to have either a specific width, specific height or both. (Thumbnails defined with a width or height of 0 can be any size).

To do this with PTE you select the post-thumbnail that you want to crop, go to the options button and then unset the aspect ratio. You can then select the part of the image you want to crop and in the options you can choose the color of the bars that would appear on the top or bottom.
