Newbie – Want photogallery in wordpress

hi everyone
i am very new to wordpress. basically i want to setup a photo gallery to show pictures which i take everyday. it’s hard for me to resize and create thumbnails in my website. i thought wordpress has some great themes which makes my life simpler and easier.

so i have created a wordpress blog under photography79.wordpress.com

i have downloaded a free theme called monotone 1.1. also found one more monotone in the themes section of my admin login. (not sure both are same or different). that monotone has a readme file which ask me to browse design or wp-content. i dont find both of them in my dashboard or any settings online. i tried to configure ftp but this username/pwd and blog url is not been taken. i hope i dont need a webhosting… coz, i am not affordable now. i just want to utilize wordpress 3gb space which is enough for me.

now when i create a post only one image am able to upload. i mean, i just want to know how i need to create archives & images into it. also, i want to disable the right click option. and if there any useful plugin for the photogallery please advise me.

i would greatly appreciate for any advise or suggestions to solve my issue. it’s really been a very tough job for me. hope i will get help form you all. thanks in advance!

best
