Hi I am have problem of uploading image.

When I try to insert image to a post, I browsed a file from my PC, clicked upload, but a message pop out as follow:

Unable to create directory /home/mydomainfolder/public_html/blog/wp-content/uploads/2009/10. Is its parent directory writable by the server?

I have no idea what can I do?

I recently have moved my blog to a new host, I don't know if this is the reason that cause the problem, before it was no problem.

Help please!!!

The file permissions for that folder must be 755, which means it's writeable by the server, so new images can be put into it. If your WP stuff was installed automatically by something like Fantastico, the permissions should have been set at that time. If you installed yourself, you just need to go back in via FTP or file manager and set the permissions.
