I found it really, really easy. Resized the picture in 'Paint' just as you do for the 'Pictures' thread, opened my Profile page, chose Albums, gave it a name e.g. Completed in 2013, clicked on 'Upload Pictures' and followed the directions from there.
I copy my resized pictures into a separate folder which I call 'Thumbnails' to make it easier to find them for uploading. Maybe the link posted by our Moderator above (QuiltnNan) has an even easier method. Good luck folks. Would love to see more Albums up and running.
