Better yet, I will post it if there are others who might be interested.
I would have to assume that you have a camera and know how to download pictures to your computer. After that it is just some clicks away. This is the way I do it and there are MANY ways.
The pictures I take are in the large format and too large to post, so I will Email them to myself. I use Internet Explorer and it will ask me if I want to reduce the size. I click on yes and Medium is already in the box for me for the size reduction. When I open my mail, there are my pictures reduced and I then right click on the pictures to save them to a file.....the pictures file is preselected for me so that is where they go and are now ready to select to put in your post. The entire process takes less than a minute and sounds far harder than it really is. Except for giving your picture a name, it is mostly mouse clicking.
Now, just a few more clicks away and you will have a post with your picture(s). In you post, click on Upload File..., click on Browse, select your picture file, Pictures, click on the picture you to post, click on OPEN, Click on Upload and if everything went right you get the message..........Your file was successfully attached to your message . I did this picture as I walked you through the process. BTW that picture makes a good wallpaper for you computer.
Good luck
