I tried posting a pic in a thread tonight. After about 5 attempts at shrinking the pic down, I decided to post it in the members pic forum page. 39.1k is what it says as far as picture size to post in a thread. When I posted it to the Members pic page, it appears there is no file size limit at this time.
the link below should take you to the members pic page that will allow you to post larger sized pics.
