Installation: Pics Not Visible

Hi,

I recently installed plogger on my server but Im not
able to see the pics when I upload them manually.

When I upload manually I get just a blank page.
the page is the admin/plog-upload.php

This is the front of the site
http://naimaalexander.com/

There is a small square that i see which if I click on
it I go to another blank page then if clicked on again
I the following message:
Warning: getimagesize(/home/breascom/public_html/naimaalexander.com/thumbs/3-3_mths_4_wks-5.JPG) [function.getimagesize]: failed to open stream: No such file or directory in /home/breascom/public_html/naimaalexander.com/plog-functions.php on line 1925

If i click on the square one more time im then taken
to the image I uploaded.

Its the same if I import.

Can you help me please?

Thanks
