Firstly, you'll have to compress the album folder into either a .zip or .rar file. I think I remember you saying that you don't have WinRAR so I'll compress mine in .zip for you. With WinRAR you do this by right-clicking on the folder and clicking "add to archive" so it should be something similar.
Now we can upload the file. You can use either Mediafire or Megaupload, but I'll probably be using Mediafire cause I like it better. It's pretty straightforward on both sites how to upload, just browse for the file on your computer and upload it. Once it's done, you can post the link on this blog and we're good to go.
