Hello,
Use Steemit.com to store the images, and then use the links to those images in other posts, your settings, and profile.
Adding photos to your account as a new Steemian may be confusing at first too. The easiest way it to click to "Submit a Story." Once in there, use the built in Steemit tool to upload an image from your computer. Below the posting window, you will see "Insert images by dragging & dropping, pasting from the clipboard, or by selecting them." Click on the blue text. Once the image is uploaded, you can copy and paste the link into your account settings.
Let me know if you have any other questions. I'll gladly help!
