I don't know what photobucket is either. I have posted a large number of pictures and do this by getting my film or my photo card (depending upon the camera used) copied/converted onto a CD at a camera shop or maybe wal mart. Then, I pic the pics I want to load onto my computer. I then load them onto the 'puter into the pictures file. I can resize them by way of the "paint" program.
When you post a reply you'll see the "manage attatchments" and this will bring up you photo file in the computer. You click on the one(s) you need to load into the post (up to five or six pics?) and then enter each one.
In the paint program, they will appear as a number like AB112329 and then you can change that to any decription you'd like such as "1993 D250 #1" and "1993 D250 #2" and so on... ... ... ...
Tip: if you post a picture you cannot ever post that picture again on this site. Ever. So, you simply change the picture description, as you had done in the paint program, to a slightly different description such as "1993 D250 #1B" then you can post it again some months later if the need would arise. You can post the same picture 100 times if needed simply by changing the decsription.
