How would one upload a picture from community to the critique?

I cannot get to the site to allow me into the community if I had to try my new email address. It continues to take me back to the Outlook/Windstream and I don’t have the Windstream account any longer and use gmail.com exclusively. I can’t seem to load the picture from the community to send it to the critique section. Do I have to open up a picture file (.jpg)? and do it that way so the page won’t disappear, I have written my comments; but, can’t seem to attach it. The subject was done from a photograph. I can load the picture to the community. Should I find the file in my .jpg file to do so?

Can someone help me?
