Calamity Jane told me about this website:
http://www.domaindlx.com/
where you can sign up and then move images from your own computer there. It is sort of an image laundry.
So, I find an image on the web, save it to My Pictures... sometimes using a clever name, though you can also rename in the above website...
then go back to that website, sign in, upload as single files. Select the one you want so you've got it in a new window...
I've noticed that a2k will only display the images that have short names.
