[rt-users] Custom Field Attachments to Templates

[Jeff Ehrenberg]

I decided to revisit this idea of including custom field photos in the
resolved email response.  I think I am close to a solution but I am getting
hung up on some formatting.
I am able to retrieve the blob data for the LargeContent field and then
base64 encode it.  From there I am putting it in to an html email and then
using an <img> tag like this:
<img src="data:image/jpg;base64,
encode_base64($customFieldValue->LargeContent, '')">

The email arrives html formatted but the problem is that there seem to be
newline characters inserted in the base64 encoded blob.  The encoded data
seems to be in groups of 989 characters before a new line.  I have tried
numerous ways to remove the newlines, but none have worked.  I am thinking
that this might have something to do with the Text::Template module?

If I remove the extra whitespace from the email and then save it as html,
the photos will display correctly.

Any ideas?
an example of what I am seeing in the html source:
<img
src="data:image/jpg;base64,_9j_4T_-RXhpZgAASUkqAAgAAAAMAA4BAgAgAAAAXAUAAA8BAgAYAAAAfAUAABABAgARAAAAlAUAABIBAwABAAAAAQAAABoBBQABAAAAKAUAABsBBQABAAAAMAUAACgBAwABAAAAAgAAADEBAgAgAAAApgUAADIBAgAUAAAASAUAABMCAwABAAAAAgAAAGmHBAABAAAAngAAAKXEBwAUAgAAyAUAACQCAAAgAJqCBQABAAAAqAgAAJ2CBQABAAAA0AgAACKIAwABAAAAAgAAACeIAwABAAAAZAAAAACQBwAEAAAAMDIyMQOQAgAUAAAAfQgAAASQAgAUAAAAkQgAAAGRBwAEAAAAAQIDAASSCgABAAAAsAgAAAWSBQABAAAAuAgAAAeSAwABAAAABQAAAAiSA
