Well I sat down try this out. To pick up a photo from Flickr and post in Forums.
1. Found the photo in Flick
2. Clicked on it to get large size.
3. Selected appropriate size
4. Clicked on "Share this Photo"
5. Clicked on "Grab the Link"
6. Copied URL which came up in square
7. Went to Forums and clicked on "Insert Image" (Small Picture of Mountain)
8. Pasted the Copied URL
9. Hit OK.
10. Hit Preview or Submit Reply.
Nothing, Zero.
This procedure is virtually what I have been doing Flickr/Forums for years.
What am I doing wrong that no picture will come up in Forums.
I must be missing something, but then, what's new?
