Bump thumbnail size to 5MB & check size before upload.

- The previous 2MB was a CDN limit (more of a mistake). That has been increased to a far greater number, so we're setting a more reasonable 5MB limit.
- The previous code checks/shows the "size exceeded" message after the file has been uploaded ... in the `catch` block. This will not work since the CDN now allows a 5MB file.
    - Fixed by checking the size before actually uploading.
