Hi Amy, I will give instructions for you and anyone else reading.
1. Have the images saved to your computer
2. When logged into Imgur, click on the letter with your initial in the upper right hand corner, then select "images" on the dropdown list.
3. This will bring you to a new page, select "Add Images" and "Browse" to upload your images.
4. Image will upload. When you select it, copy the line for "Linked BCC Code"
5. Use this in your post where you want the image, it will appear as text until you submit the post.
