Cannot Transfer Photos from DSi to Original DS — Hardware Incompatibility

Direct transfer is impossible. Original DS/DS Lite lack an SD slot and cannot receive files via PictoChat (text only).

Workarounds

1. SD Card → PC → SD Card (for DSi/3DS only): Copy photos to PC, then to another SD for DSi/3DS. Does not work on original DS.
2. PictoChat (DSi ↔ DS/DSi): Send low-res (256x192) graffiti-style images frame-by-frame. Tedious.
3. Facebook/Flipnote Hatena (DSi only): Upload from DSi → View on PC/Phone. Original DS cannot access.

Best path: Keep photos on DSi/3DS/PC. Original DS cannot view photos natively.
