Facebook Graph API /me/feed posts cannot change link picture size -


my web app posts updates facebook users feed using graph api. api allows specify text 'message' , '\n' in text result in newline. api allows 1 specify link url , link picture, have set app url , logo image. 1 can specify link description, '\n' in text description not result in newline.

there 2 unresolved issues i'm unable find answers...

1) facebook refuses show logo image in post size less 154x154. i've tried submitting many size logos including larger, smaller, wider, higher. nothing results in image anywhere near 100x100 size i'd show.

2) 154x154 image ok, if put newlines in link description, shows right of square image. puts text on 1 line. tried '\n', '%0a', , padding ' ', ...

any idea how solve #1 , if not... solve #2?
