HI Theresa, to put pictures on this site, just go to your home page, then at the bottom of the text box you will see a blue link that says "post photo or video".
click on that, then the box will open and you will see the cursor blinking beside a link that says "browse". Click on the browse button and you will be taken to your computer where you can select a picture to upload. After you select the picture, click the share button on the bottom of the box. The picture will load on the site. This takes a few seconds, so be patient.
Let us know if you need help with anything.
