Get a Flickr account. It is what I switched to when my photo bucket filled (which was shortly before the hosting ransom BS started).
With Flickr I can upload photos, find them in my Flickr account click photo, click the 'share' arrow (select BB code once and it will remember to use it), select the desired image size to embed here, copy the BB code from there to here and done.
My flickr pictures are all clickable to full rez versions. Being able to select size has it's advantages too. I can have a large screen filling picture to show detail/for dramatic effect, I can select midsize images and (with some pruning of their BB code) have 4 mid size images side by side on a page (great for screenshots, chassis pictures, and process progress sequences), or I can have a teeny tiny thumbnail for when I've got a tangentially related pic I don't want to distract from the main subject.
To illustrate a picture of my 21CT55 (and other sets):
There are bigger smaller and many inbetween sizes too, but this should give you the idea.
