Tenhle skript celkem za nic nemůže, jen mění velikost požadovaného obrázku.
Dal by se upravit skript na vkládání nových článků, aby z vloženého obrázku udělal a uložit miniaturu (maximální šířka či výška bude jistě definovatelná). Pak by se obrázky četly přímo ze složky s miniaturami. Jen je nepříjemné, že potřebujete tři různé velikosti obrázku od každého - to by (trochu) zpomalilo ukládání nových článků. Na druhou stranu by ale server nepadal.

Ale je to jen nápad - nepracovala jsem s WP, takže nevím, jak složité by to bylo.
