Legenda aparecer quando imagem carregar

Tenho esta AS e quero fazer com que o texto(texto dinamico, instaciado "txt) que esta dentro deste movie clip, instanciado "info_mc" apareça sempre que clicar nos thumbnails (menu_mc) ou na setas (bttnPrev, bttnNext)

Do jeito que está a AS, o texto só aparece quando o mouse é colocado em cima da imagem carregada.Se tirar o mouse de cima da imagem a legenda some.

Quero que a legenda apareça assim que a imagem carregue. e permaneça até chamar outra imagem.
