Copy/pasted images in Froala editor (Mail body, signature, etc) and GMail

Hello,

When our customers paste an image in their e-mail (or in their signature) it is converted as

<img data-fr-image-pasted=3D"true" src=3D"data:image/png=
;base64,__base64string__">

While this seems to work when the mails are received in different mail clients (at least emClient, Outlook), it seems that the images are not displayed in GMail.

On another hand, on GMail our customers receive other mails with inline images that are displaying correctly.

Anyone else has experienced this issue. Personally I was able to replicate it. Now I don't know how it could be fixed. Should something be done SmarterMail side or GMail side ? huh

EDIT: I did a quick test to add an image to my Outlook and my eMClient signature (pasting the image like I do in SmarterMail) and then send a mail from both clients to a GMail address. They display correctly in GMail. Only the inline images sent from SmarterMail doesn't display :/

Result in eMClient:

Result in GMail:

The difference between SmarterMail's webmail and the other mail clients about inserting inline images is that SmarterMail includes the base64 content in the img tag (doesn't work on gmail). The other mail clients use attachments and reference the cid in the img tag (works everywhere)

<img src=3D"cid:em9dac1=
900-2e6b-4130-b3c9-b7d9154abb73@hal9000" border=3D"0" />

Is that maybe a configurable setting in Froala editor to use one or the other method when composing the mail content ?

It would be very nice they switch to the method supported everywhere...

EDIT: Also an article about base64 images inclusion. It says it's better store the images somewhere and reference them with a link, because of massive slowdowns (I experienced it when playing with signatures containing images in SmarterMail)

I think that's what gmail is doing when you include images in a signature or a mail.
