Error trying to upload images

Hi there ??

I’m getting this error message when I try to upload images to my blog post:

“The uploaded file could not be moved to /home/gris/public_html/blog/wp-content/uploads/2008/10.”

I’ve never had trouble uploading images before and have been doing so successfully for over 2 years now. What could be causing this?

Thanks for any insight!
