20 uploads in gallery

I have made some changes with numbers of uploads, but there is a problem.

This allows you to specify how many file upload fields appear on the image upload form. By default, only 5 fields are provided. We recommend you do not have more than 5 fields if you are on a shared host or have limited resourced. If you incress this to more than 5, we highly recommend you test this by uploading lots of large files before putting your site into production.
