Can't upload photo attachments to posts

[rockabilly]

Hello,
I am trying to upload a jpg file to my fresh install of vb4.2.2. When the photo uploads, it displays a red exclamation point and says "invalid file".
It's not an invalid file, because jpg files are allowed, just as other files are allowed. I have tried png files, gif, etc. and I keep getting the same error message. Any ideas on how to fix this?
Attached is a screen shot from my file uploader. Thanks in advance.

Howver over the ! icon, what does the error say?

It says "Invalid File". I can figure out why this does this when all the file extensions are allowed. I have tried uploading several different file extensions, and still the same error message.

Does your php installation have cURL?

I am not familiar with cURL,but I am running VB on a VPS with cpanel that has phpMyAdmin.

If its managed, ask your webhost. If its not, you'll need to look into recompiling PHP with cURL support.
