I tried to attach a photo to my post. The picture is 241 KB (not MB) in size. The first time I tried this, I received a error message that said I could not upload photos 1 MB or larger. I checked the size of my picture again. It is 241KB. I tired a second time. I received the same error message.
We have exceeded our upload allotment and decided to not pay extra to increase space. The best way for you is to put your picture on any web site (there are lots of free photo hosting sites) and then just put the link in your post.
