If I may offer a clarification of the steps to follow in Photobucket...
If you're in an album in Photobucket, just hover your cursor over the image with your mouse. A popup will open with info for sharing the image in other webpages. I copy the image tag (starts with "img") and paste that URL into my posts on other websites.
If you click on the image in an album in photobucket, you'll be navigated to the specific page for that image, the "detail" page, if you like, and on the right-hand side of the page, you'll see a box labelled Links. Again, I use the image code URL, which allows me to embed the image in a post, just personal preference.
Hope that helps!
