Pictures

I am new to using a blog. I am still trying to figure things out so be patient. I would like to make a slide show of progress along my way, but it appears that I can only download a slide show using an url instead of selecting pictures from my computer. So for the time, I am just going to take pictures and post them one at a time with an update. If anyone has any suggestions for how to set up the slide show, please share. Thank you.
