I honestly don't know why more people don't use Flickr. I never get any spam, there is very limited, if any, ads...
It is a bit different to use than PBucket, but once you get used to it there is no problem. I have used it since I joined up nearly 3 years ago...
To share a pic you just open the picture you want, click on the little bent arrow in the bottom right hand corner, select "BB Code" and what size you want, I recommend the "Medium 640" setting and copy and paste the code. Once you have used it once it saves your code settings for you and it will always come up "BBCode" and "640".
You will get a long code which will leave a tag under your photo like this:
