1.5.10 has same problem as 1.5.9 - will not show thumbnails or photos

The following information is required to get an answer:
Get this information from the PHP diagnostic (in the configuration wizard).
Gallery URL (optional but very useful):
Gallery version:
Apache version:
PHP version (don't just say PHP 4, please):

All info same as post in thread - "Yet another "No Thumbnail" or even showing Photos"

All I did was install 1.5.10, all else same, please see other thread....
