Sorry folks, I just realized that photobucket has suspended my account for the rest of this month (5 days left).
I checked my account info and found out that I have had about 25,000 hits in this last week and that, in just one week, I have apparently exceeded my "photobucket bandwidth allocation for the entire month of May.
Frankly, until a few minutes ago, I had no idea that bandwidth would be a problem.
I have written the hosting service (photobucket) to see whether the account can be activated immediately. I am waiting for an answer.
As I suspect that I will run into this same problem in the future, I am considering alternative/supplementary hosting services.
Suggestions greatly appreciated....
