NewsletterBuilder and Images
Hmm, yea that's a curious one. I haven't seen that issue before. You could examine the source of the messages received by the email applications, as well as the source of the HTML under the log here: admin.php?menu=_outgoing_mail (you may need to enable logging)
There are some options for including relative or absolute URLs, but it sounds like the issue you're having is that files are being renamed to lowercase on upload? So the message source references potentially mixed case files and the uploaded files are all lowercase?
Can you confirm that? And if so confirm if it's lowercasing just the filename or the filename and ext. For example, does FILENAME.GIF become filename.gif.
I'm not aware of anything that would be cause the files to be renamed, but if you can confirm it we can look into it further.
Let me know what you find out!
Hi, Dave. Thanks for the reply.
It seems that when I add an image to the WYSIWYG editor in NLB message, the nme oif the file is immediately changed to all lowercase.
e.g. CMECalendarQR.png, becomes cmecalendarqr.png. (This happens for CMECalendarQR.PNG as well)
This change is refelected immediately in the tinyMCE editor and comes across in the raw code of the received email.
When the remote server is checked via FTP, the uploads folder for CMSB also has cmecalendarqr.png, and so one wonders why the file as referenced in the email does not appear.
<div class=3D"content"><p><img src=3D"https://nypq=
cme.org/cmsCSoft/uploads/cmecalendarqr2.png" width=3D"410" height=3D"422" a=
lt=3D"" /></p><br /><br /></div>
While my first assumption was that this was a path or case error, it doesn't appear so based upon this.
Ok, I did some tests and it does seem that we lowercase the upload filenames, so it's something else.
Can you fill out a second level support request or send me an email direct at email@example.com and I'll take a look?
After a fresh install of Thunderbird, I find I am able to see images sent in the mailings. However, no amount of messing with the settings of Mac Mail will show ther images.
In any event, this issue should be closed for you guys.
If anyone has encountered this behavior on a Mac, your advice would be appreciated!
It seems that another issue occurs that may be related to this one.
I get the following error sent to me when a .png file is uploaded to the newsletter.

E_WARNING: imagecreatefrompng(): gd-png: libpng warning: Interlace handling should be turned on when using png_read_image
/home/pgplast/public_html/cmsCSoft/lib/image_functions.php (line 42)
I don't have a Mac, but maybe double-check these settings:
- Load Remote Content in Messages: Go to Mail > Preferences > Security. Check the box next to "Load remote content in messages."
- Display Remote Images in Individual Emails: When you open an email with remote content, look for a banner at the top of the email. Click the "Load remote content" button to manually load the images for that specific email.
- Also check this page about the "protect mail activity" setting: https://support.apple.com/en-ca/guide/mail/mlhl03be2866/mac
For the warning, can you let me know if you're running the latest version of CMSB? And/or add a @ in front of imagecreatefrompng on the line number reported by the error?
case IMAGETYPE_PNG: $sourceImage = @imagecreatefrompng($sourcePath); break;
I think that one is a bug in the underlying code and not indicative of an error.
If you have @ in front and it's still reporting errors let us know.
