Scott,
It's not hard and doesn't need to be intimidating. I don't use photo bucket.
What you do is download the photo that you take with your camera to the section of your computer that holds the photos. For example, in the case of Microsoft software, that would be My Pictures. You may have to resize the photos, which is not hard.
Then, when you want to post photos on the Forum, start a new post and then go to Manage Attachments at the bottom of the post. When you click on that, it will open a new window, then go to Add Files and click on that. You will click the Browse button and find the area of your computer that holds your pictures.
By the way, this works with smartphones. I use my iPhone to post photos on the Forum. If you have an iPhone or an iPad, you need to get an app like Simple Resize so you can resize your photos.
Hope that helps.
Brad
