## Start with Original PSD/AI/etc. or High Resolution 24-bit PNG

- If you contract out: get the original/source files!
  Keep track of them!
  Make sure others know!
- Always start with the original file format (e.g. PSD, AI, etc.) or high-resolution 24-bit PNG.
- Size images accordingly!
  - Don't shrink full-resolution images by using "height" and "width" CSS
  - Don't enlarge images from smaller ones -- you can only go one way (larger to smaller)
