In the new Thunderbird 52.0, changing the preference "mail.compose.attach_http_images" to true does not allow me to attach my image (esignature). How can I fix?

I used to have my signature/esignature automatically attach to my email messages, I thought from a folder on my computer (jpeg image).

I recently got the upgrade for Thunderbird 52.0, and ran through the process to change "mail.compose.attach_http_images" to true; however, my signature does not attach.

All that shows up is a broken image type of graphic. I can change on an individual message basis, but that is very cumbersome each and every time.

How can I have my image attach for my signature automatically like it did before?

Thanks for that link, but that wasn't the instruction I was looking for.

It did lead to me figuring it out: and I think this is what non-super tech minded users like myself might find useful:

Once you convert your code, here is what you do with it:

>go to tools >go to account settings on the initial account settings screen (for your email)

>uncheck "attach the signature from a file instead"
>and check/select "Use HTML", and in that "Signature text:" box, copy and paste your data URI code. 

That should get it!

You have to convert your file to the data URI format.

Thanks. I went online and found a converter that converted my image to data URI.

It provided a ton of lines of code - what do I do with this/where do I copy and paste this?

I was expecting another file (data URI file), but just got this code. As you can tell I am not a programmer/computer literate at an advanced level, sorry.

If you recreate you signature, does it attach without errors?
