query for changing multiple records?

I have a database containing a table with records of pictures in an album. I have moved many of these pictures to another location and need to reflect that change in my database.

The problem is that I'm using phpMyadmin and cannot change all of the 68 records at once. Is there a query I can write or a php script I can use to make the change?

I have no knowledge of MySQL or of php programming. I'd appreciate any help you can offer.

update <table> set <fieldname> = 'new/path';

If you do not give it a limiting clause, like "where" then it will update all the records in the table.
