They won't be viewable on a DSi. Jpeg photos created by DSi contain a special EXIF tag with an AES-CCM MAC of the entire jpeg file, which the DSi will verify first before viewing. Normal jpeg photos, not created by a DSi, do not contain this tag, and will be rejected by the DSi. The same applies for tampered DSi jpeg photos because the stored MAC will not match.
