I really wish everyone on here would use google photos (Picasa) instead of Photobucket. Photobucket is a massive pain, it doesn't display photos in a large format on this site, and when you click into a photo to enlarge, it takes you to a normal size resolution, then you have to click again (maybe it's several time) to get to original resolution.
With Picasa, you right click on the image and select "copy hyperlink location" or go to Properties and copy url, then just paste that into your thread. Here's an example:
Maybe the same amount of clicks to post a photo, but for the person looking at your thread it makes it easier to view the original image size.
