Tripped across this post while researching this as I had this same issue. After much playing around I determined that any computers I had using DHCP from my router worked fine, but any that I had the router's address hard-coded for DNS using the router's address (in my case 192.168.1.1) could not access photobucket. I changed the DNS servers to the ISP's servers and it works again. You could also set your computer to use DHCP and accomplish the same thing. If that doesn't solve your issue, then your ISP probably has the same problem, call them. Good luck.

VERY strange, indeed. I must admit I'm loath to visit photobucket again, for I can't imagine it was just coincidence that the only 2 times I've gotten that durn antivirus junk was when I was there. I guess, though, I'll have to try it again....glad to hear you didn't have the problem and hope I won't, again, either.

From Photobucket's FAQs: What is Bandwidth? Bandwidth is used when digital content is viewed from a link you posted on another website or sent in an email (e.g., MySpace, eBay, message boards, etc.). Bandwidth is a measure of the number of bytes passed over time via direct linking. It is calculated by adding up the size of each of your images or videos as they are sent from Photobucket. The "Monthly Bandwidth" number is the amount of bandwidth you have used within the last month. The month is determined by the day of the month you registered your account. Example: You have various images of 25K each in size that are viewed by 100 users on your favorite message board in one day. You also have one video of 15000K that is viewed by 10 users in one day. 25K * 100 requests = 2500K (or 2.5MB). 15000K * 10 requests = 150000K (or 150MB). When you add the two together, you have used 152.5MB of bandwidth in one day. Important! Do not confuse bandwidth with your album size. Bandwidth usage is unmetered for Pro accounts, however Photobucket reserves the right to disable direct linking on accounts that use excessive bandwidth or are otherwise abusing the system. To check your current usage, log into your account, click the account options link, and then review your Monthly Bandwidth in the Account Dashboard to the right. Free accounts are allowed 10GB of bandwidth per month, and Pro accounts are unmetered. 10GB is hundreds of thousands of images viewed via direct links, and the value resets each month on the anniversary of the day you registered. My note - remember, regardless of how many 'posts' your thread may have, thousands if not hundreds of thousands of people may have viewed it. GW membership is required only if you want to post. Anyone on the internet can read it.

Sorry for the problems. I only uploaded my recent post for design help and had no problems.
