Can you post their instructions here? Somebody should be able to explain it to you in simpler terms.

I use imagecave.com and haven't had any problems with it.

Thank you, Bob.

Here are the instructions from Photobucket:

On Mac OS X:

Type lookupd -flushcache in your terminal to flush the DNS resolver cache. (ex: bash-2.05a$ lookupd -flushcache)
Once you run the command your DNS cache (in Mac OS X) will flush.
Once the above suggestions have been tried, please try logging into and using your Photobucket account again.

If the problems persist, please click the contact us link below and provide a detailed description of the problem you are experiencing. Please be sure to include details for any steps you have already attempted to resolve the problem.

I don’t even understand WHERE in my “terminal” I’m supposed to start typing.

In any event, I’m afraid my Mac which has run without ANY problem or breakdown for about 7 years will be “terminally” dead.
