Is there any way to include the HTML codes to obtain mathematical symbols e.g., π ∞ or ∑ etc., so that we can see the actual symbols in our postings?

I was hoping that one can just enter the Unicode characters for these directly but the forum preview renders them as html codes (e.g. these are Unicode symbols π ∞ ∑). ▼

That is a clever solution, but fragile. If the MoHPC web site could duplicate the PNG symbol web page locally then links to symbols in postings would not break if the original site changes or disappears.
The copyright terms of the original page seem to allow this: All images and text displayed on this web page are placed in the public domain by the author, per the Creative Commons Public Domain Dedication [external]."

Hi. What a finding! C'est magnifique! Thanks for sharing, I was not aware of that - and the page was last revised in January 2008... (reminds me the deep web and the Onion browser; what the f*** do we know) I for one have now a pot of gold, will use this resource pretty often, not only here but elsewhere. Merci!

Online Latex may be the way to go.. I do not know how to import images onto a message. :( Eddie ▼

There a button called (Image) right below of the editing window ;-) ▼

It's only now that I realize that you can select URL encoded in the box at the bottom. Cool!
Thanks for pointing that out.
PS: You can safely ignore my post bellow. I didn't understand you correctly.
Quote: Not exactly. It's a link to latex.codecogs.com. When the site is down the image can't be shown. Embedding it as base64 encoded data URI would make it permanent.
Kind regards PS: IIRC it's possible to get access to an ftp-account and upload files to this forum from where they can be linked to.

So that is the secret.
Thanks C. Ret.

You could save the image and convert it into a base64 string:
<img alt="" src="data:image/gif;base64,R0lGODlhVQASAIQAAP///wAAAKCgoLCwsMDAwJCQkPDw8FBQUNDQ0ICAgODg4BAQEEBAQCAgIHBwcGBgYDAwMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAAAALAAAAABVABIAAAX+ICCOpKGQaKqubOu+7jDAdG3feK7vtHKKhGDQwCsaSQgEA2BwJBiPR4J4BCAgVdJAQCggWARFA0AgDwplWNhFSCQCWdHgMYL8VI7C6GFIpF9+anBxEHoiBw4sDQp6BlgHMzCBLwSDWQF/TyMCA12HAkQFegUJNJNslkeVmXAGB18ApzuyYKkpBwy5uruJKKsjbwAHpYdUPLQrlXG/Im8KAVwyxje7DA0QvMm2RcyxmAtxzX8tyiwIQuhCsCWYwBAESyPTs+O1LW74+W4CKg38IlEAjBFhoMC8HMhUlMuSgI6IBmUQ+NlyEGG9FG0OBHByx4iDMgX+hRM30oYCAhUHsyhIWfJFCAA7" /> Unfortunately we can't include an image using a Data URI.
