If you haven’t worked it out yet, the URL is for external photo hosting sites. Much simpler is just copy and pasting a Jpeg or Png file into your reply, just like text. But please don't post big, multi-megabyte files. They take forever to load. You can easily downsize them. I find 600 to 1000 kb files display quickly and clearly.I'm new to this forum and i find it difficult to upload a picture. When i clicked on the image icon it asked for url.
