How to show image in ticket history or articles?

1

Hi,

I dont understand how to show image in ticket history and articles.

I can see images during articles edit or ticket reply/comment in CKEditor. My user receive images as inline encoded in base64 in mail.

In ticket history i can see image when i download the html source.

But image dont show web UI and i’m unable to find the option needed to show image in ticket history.

In my RT_SiteConfig.pm i have those options:
Set($ShowRemoteImages, 1);
Set($ShowTransactionImages, 1);
Set($PreferRichText, 1);

Any idea?

Kind regards,

Edit: the problem concern images inserted via copy/past in CKEditor. Images receveived by mail are visible in ticket history.

Hi. For me it’s enough (RT 5.0.5):
Set($ShowTransactionImages, 1);

I can’t find $ShowInlineImages in the code. Is it a new setting in 5.0.6?

I also don’t have ShowInlineImages and I’ve searched my rt5.0.6 build.

Also, the setting Set($ShowTransactionImages, 1); is default and I’ve never had to mess with any of it, and I see all attached images inline in the ticket history/transaction log. It just seems to work as always.

Hi, the first 2 answers come from bot, that why they gave false info about value who does not exist.

In my case i see attached inline image from answer comming by mail, but i dont see my own image in ticket transaction when image was copy/pasted in ckeditor with an anwser from web gui.

Users receive my answer with my image copy/pasted, but it does not appear in ticket history in the web gui. I’m in RT 5.0.6.

I have something working now, but i dont know if it can cause a security issue.

Create an overlay by copying the file /opt/rt5/lib/RT/Interface/Web/Scrubber.pm to /opt/rt5/lib/RT/Interface/Web/Scrubber_Local.pm

Edit the file
/opt/rt5/lib/RT/Interface/Web/Scrubber_Local.pm

Change the line (or comment)
push @src, qr/^cid:/i
by
push @src, qr/^cid:|^data:/i

    if ( !$RULES{'img'} && ( RT->Config->Get('ShowTransactionImages') or RT->Config->Get('ShowRemoteImages') ) ) {
        my @src;
#        push @src, qr/^cid:/i
        push @src, qr/^cid:|^data:/i
            if RT->Config->Get('ShowTransactionImages');

Kind regards,

When you paste an image into CKEditor, it’s often embedded as a Base64-encoded string. While email clients may render these images correctly, the ticket history viewer in your RT web interface might not support rendering Base64-encoded images by default.

I’ve tried to copy/paste from the RT editor and it doesn’t work for me too.
I’ve tried @periway’s overlay but it doesn’t work for me. I can see in the source:

<img src="data:image/png;base64,iVfh7kjs7...

And the UI says that the message is too big to show it. It seems that history can’t show embedded inline images in base64.

Following this thread:

I’ve set MaxInlineBody to 0, reloaded the ticket and now I can see the inline image.

Update: @periway’s overlay is also needed.

Couldn’t find a way for this to work in articles. I’ve tried too adding a custom field to upload files and then link to them as said in RT 5.0: is there a way to insert picture in Articles? without luck.

Hi,

For articles i have a custom field applyed on all my articles classes:

Name “content HTML”
Type : “Fill in one HTML area”
Applyed : “Articles”
Activated

On my article class:

Name of class : “xxxx”
Activated
Include custom field “Content HTML value”

Now create the overlay needed:

mkdir -p /opt/rt5/local/lib/RT/Interface/Web
vi /opt/rt5/local/lib/RT/Interface/Web/Scrubber_Local.pm

Insert the code bellow (i’ve found it on GIT of easter-egg www.request-tracker.fr) in the Scrubber_Local.pm file:

package RT::Interface::Web::Scrubber;
$RULES{‘img’}->{‘src’} .= “|”.qr/^cid:|^data:/i if RT->Config->Get(‘ShowTransactionImages’);
1;

On your RT_SiteConfig.pm you need to add this policy:

Set(
%ScrubCustomFieldOnSave,
Default => 0,
‘RT::Ticket’ => 1,
‘RT::Transaction’ => 1,
);

I hope this can help.

Kind regard,
