CMS Where can I set the values for Large, Medium & Thumbnail image sizes?
 

OK, we have been using the CMS system and have started to play more with tweaking the articles. One feature we like is the inline photo, but we want to change the resizing of the image attachments. Where can I change the settings for what is used for "Large" "Medium" (300px) or "Thumbnail" (150px) sizes of the images?

I looked around in the admin area and searched the forums but couldn't find an answer.

TIA.
