Hi there BB. I am with btinternet and have free space with them. Every BT customer gets I think 50mgs free web-space to do what you wish.
First you need to get your web-space. Go to the btinternet home page and look for the excellent HELP bit to get you through. It is basically as above. For uploading, you will need to use something like CUTE Ftp. I think but am not too sure that BT only supports Cute and Smart FTP only. You need one of them for easy uploading, it is like a windows explorer interface, your computer stuff on your hard drive in the colum on the left and what is on your web-space on the right. Find your pictures in the left box and either double click them or click it and press the upload button, its a piece of cake.
Once you get into it, buy a domain name for about £7 and link that to your free bt page, thats pretty cool if you do that. For example, mine is
http://www.evo.me.uk and if you click on that it will take you straight to my bt pages. Yours could be something like "boeingboy.com" or something similar. Good luck.
