Just occurred to me that ‘pictiúir’ is for whatever reason not put in the tuiseal ginideach after ‘sraith’. Aren’t nouns that are being used as adjectives (i.e. ‘scoile’ in ‘bus scoile’) supposed to be put into the T.G.?
Tá “sraith pictiúr” mícheart i mo thuairim fhéin. Bheadh sé ceart dá mbeadh sé mar “sraith phictiúir”. Ceapaim go dtagann “sraith pictiúr” óna gcúpla focal.
Athbhliain faoi mhaise dhaoibh uilig! Actually, ‘pictiúr’ is in the genitive case here, but it’s genitive plural, rather than genitive singular (like in “leithreas na bhfear” – men’s toilet = the gents). That’s also the reason why there’s no lenition on “pictiúr”. As a rule, nouns following a feminine noun (like ‘sraith’) are lenited, but that does not apply if they are in plural (also “sraith clár”, not “chlár” – “a series of programmes”).
