[Plugin: Contact Form 7] Captcha image not displaying on form

Captcha image not displaying on my form. In the admin area, I’m getting the message “This contact form contains CAPTCHA fields, but the temporary folder for the files (/home2/les/public_html/ultimate/wp-content/uploads/wpcf7_captcha) does not exist or is not writable. You can create the folder or change its permission manually.”

However, the directory identified does exist and is writable. Is there supposed to be a folder or file after the …/uploads/wpcf7_captcha?

Does anyone know what the problem might be?

Thanks!
