I can't believe I can't figure this out, or how much time I've spent on it. I have some extremely large images showing up and I can't get them to resize. I've attached a screenshot so you can see what I'm talking about. Here's the deal:
I have a menu item linked to some K2 Categories. There are some options under the Joomla menu editor where I can set the categories it links to and set the "image size for leading items" and "image size for primary items" etc. I've set them to small to no effect.

I've also gone into the K2 Categories editor. I've fiddled with every parameter and set all the images to small in the "Category Item Layout". No effect. I've also set the "item image options" to specify the the image to be 100pix wide. No effect.

I'm pretty convinced this must be a bug. Anybody have any ideas?

I figured it out. There was a subcategory and there was where the settings were coming from. That took WAY too long to figure out.
