To do this effect, follow the steps below:
1. Get a dropbox account - visit dropbox.com
2. Upload a photo to your public folder in dropbox
3. Select the photo you just uploaded (automatically selected sha)
4. Create a public url of the photo - it will give you something like this - https:///I09iTnoO
5. Paste that public url to nairaland - highlight it and click the image button
This will surround the selection with an image tag giving you something like this:
[img]https:///I09iTnoO[/img] - for some unknown or mysterious reasons (a bug likely), if you use an image that starts with secure protocol i.e. https, nairaland will not show it and will just display the entire image link as shown.

But if you try removing the extra s and have it like this (minus the spaces): [ img]http:///I09iTnoO[/img] - note that i added the spaces to confuse nairaland, you shall surely get this:

[img]http:///I09iTnoO[/img]

Claro?

I did a little research for you, here it is: highlight the text you want to hyperlink, and click on the hyperlink button in the editor menu, it the globe button you can see there, then next you will see something like this "[url] click here[/url]" , do this next: add an equal sign followed by the link/address you wish to link to in the first bracket. it should look like this now
