ExtendSync provides the ability to optionally attach files to NetSuite records. This link provides a short overview of the process.
Keep in mind!
For an email, the individual attachment file that is supported is up to 10 MB.
The total email size limit should not exceed 25 MB.

Hosted images
Hosted images will always transfer to the email in NetSuite. With a hosted image, the file size of the email itself is much smaller (because it does not include the image data inside the email itself), meaning the email will take up less storage for both the sender and the recipient. The images are generally stored externally on a public server and made visible via HTML.
Inline (or embedded) images
Inline (embedded) images will only transfer to the email in NetSuite if the user selects to include it as part of the file attachment process. It will not be visible on the email message itself but can be found by clicking the attachments tab on the NetSuite email. These images will occupy NetSuite storage space.
File Attachments
File attachments will only transfer to the email in NetSuite if the user selects to include it as part of the file attachment process. File attachments will occupy NetSuite storage space.
