Hi, I've made an application to select which Gmail account to send a message from. When you share images/videos via Gmail or click mailto link, your account is chosen automatically and you can't change it. Select Gmail Selector instead of Gmail. you can choose which account to send a message from. Add Gmail accounts to the app before you use it. Works on 2.0-2.1 only. It's a paid app. Try searching "Gmail Selector" on the market. Thanks.
