Could use some input on this. Would data URIs be useful for you in WriteFreely? Or not needed?
@Cochise Yep, stored in the DB as `text`: https://github.com/writeas/writefreely/blob/v0.8.1/schema.sql#L139
For Snap.as images are stored on the filesystem / with an efficient delivery system. I agree data URIs aren't the best solution for photo hosting -- both for storage and for reading content (since the data can't be cached).
