Dumb question time

I am thinking about using flickr in lieu of photobucket and can't seem to link my photos tyo htis or any site.
Please help
TIA

Select the picture you want to link.
Right click and select the large size. It's POTN friendly.
Right click the large image and select "copy image location."

In the post click the icon that looks like a picture and paste in the link.
Done.

or on flickr, click share, and it will give you the code, just copy and paste.

I've been using photobucket for years without problems & your images look OK here, so what's really the problem?
