gallery plugins

hello 🙂
i’m just getting in touch with wordpress and i have some ideas and plans which i’ll try to do, but i need some help.

i have wordpress installed with ‘digital statement’ theme and my questions (plans) are about the flickrRSS. I know this is not a place where i can ask you about the digital statement, but i’m gonna ask you something else 🙂

#1 i want to set up a post thumbnail. Ok, that’s easy, but can i set an image to label so that every new post with an existing label have an automatically added image. If the label don’t exist, create only once.

#2 as this is done, i want some plugin to automatically generate a ‘gallery’ with images linking labels

#3 finally i want flickrrss plugin to show me images from my gallery, not from flickr

i hope everything is fine with this post, if not— please tell me what to correct but don’t delete my post 🙂 thanks
