email template is disturbing when image is post through form submission.

hi, I have installed “Drag and Drop Multiple File Upload – Contact Form 7″ plugin.

I have set up template for email tab in contact form 7. I have added table layout. like this one
<table class=”qoute-frm” cellpadding=”5″ width=”600″>
and also check “Use HTML content type”.

1)There is one issue. I did not make file upload input as a required field. If user will not upload or drag image then form will post as well and same for uploading image.but when i Receive email on both cases, there is a width issue.

This link is for email without image. “https://imgur.com/li7S3xa&#8221;.

This link is for email with image upload. https://imgur.com/YaS8Tb3

You can also see that there is a width issue. but on backend same structure is applied. Please guide me how to resolve this one.

2) Can it be possible that image preview will also show?

Please tell me about these two things mentioned above.
