WP image resizing?

Hey all. I’m currently trying to create a blogroll page that showcases the buttons of all the blogs I frequent. I’m using each blog’s image (created by the owner) so they are of varying sizes. I’ve specified that I want each button to be 150x150 in the image properties and some have worked just fine and others haven’t…WordPress appears to be automatically resizing them and I can’t figure out a rhyme or reason for why.

Any ideas/suggestions on what I can do to override the issue without having to just make completely new buttons myself?

WordPress auto-resizes based on those settings in media settings, which I’m presuming is where you set them, but also based on your theme.

One thing to keep in mind, if you check ‘Crop thumbnail to exact dimensions (normally thumbnails are proportional)’ and the math on a resize doesn’t work correctly, you may end up with weird sizes.

What are the original sizes of the images that aren’t being cropped right?
