Why am I still finding formats I've opted to exclude?
Many of our images are available in multiple file formats. When you select or deselect formats in your search preferences, you are really choosing which ones you want to INCLUDE in your results, not EXCLUDE.
Say you're looking for a GIF. You deselect
everything but GIF, do your search, and get 27 matches. All 27 of these images will be available as GIFs; some of them may also be available in JPEG, PSD, EPS, or WMF.
