I have a problem accesing post #1362057 full-size image. The page loads well and the resized image shows ok, but when I hit 'view original', the original sized image doesn't load. Trying to download the image from the left menu gives a 403 error.
While I'm not sure if this thread is the best for this error, I'm sure it's ok to suggest here to do and run some script from the admin side which ensures that every single file which must exist does actually exist, and can be publically accessed (when it should be). My unix days were like a century ago, but I'm sure among the admins and devs there are some people capable of doing this if you think it's worth it. Think of it as part of that 2%.
