You can add large files in Gmail. This can be done via Google Drive. The drive attaches it as a link or as an attachment.
Google released Gmail in 2004 as a free webmail product. They have since added many features to Gmail, including Google Drive, Google Hangouts, Google Buzz, and more. Paul Buchheit was the developer who built the first version of Gmail, allegedly in only one day.
As far as I know, you cannot change Google Drive's background. You can only change Chrome and Gmail backgrounds.
Google Gmail has an easy to use compose feature, Google drive integration to email files up to 10GB, custom themes and a video chat feature. It is all free when you sign up for a Gmail account.
You can easily upload a video on Gmail. You can do that by attaching it on the Gmail site. The attachment could be done via Google Drive too.
You can put something on Gmail by attaching it. An attachment is any file from computer. It can also be attached from the Google Drive.
Signing up for Gtalk or Google Talk takes the same Gmail ID. One Gmail ID can be used for every Google Product. Be it YouTube, Google Drive, Docs etc.
Earlier sending files greater than 25 MB was not possible. It is not because of Google Drive. You can attach the file as a link to the Google Drive.
There is no direct link from Gmail to Google. You can insert in the URL bar to go to Google. Gmail itself is a product of Google.
G in gmail stands for = Google
You can delete images from Google drive cloud using the Cloud Gallery manager which allows you to manage your contents and delete as well on the Google drive cloud.
Gmail is short term for google mail. It is email run by google. So technically it's email with less spam and junk.
