Server setting or permissions issue with getimagesize function not working properly

[siliconfinance]

EDIT: Mods feel free to move this to the server subforum if that is where its supposed to be.

Ok, well I am here because my host (I have a dedicated/unmanaged server) says I need to update something with respect to Apache to fix my problem and I am clueless about what to do.

Basically, I get this error:

Warning: getimagesize(url edited out) [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in [path]/path to file edited out on line 51

I thought it was a permissions issue because I get a 403 error if I try to navigate to the image by pasting the URL into my browser. However, when I am logged into the password protected admincp and click a link to the same image from within the admin panel, I don't the 403 error.

Can anybody help and shed some light on this? or share any thoughts?

Seems to be related to the Image Processing (GD) functions. I can't offer much more help beyond that, maybe someone with a little more experience can give you more help.

The server doesn't know the username and password to a password protected directory so you get a 403 (or no access) if it is connecting by HTTP.
