Image hash code in description of forum topic shared on Facebook/Twitter



Image hash codes are appearing in og:description and twitter:description tags.

<meta property="og:description" content="[58C86A72-CC43-4B36-A8C7-2F360BBA228E]  One Tree Hill, Honor Oak   🎉 Welcome to Lewisham  ..." />
<meta name="twitter:description" content="[58C86A72-CC43-4B36-A8C7-2F360BBA228E]  One Tree Hill, Honor Oak   🎉 Welcome to Lewisham ..." />

It’s rare, if ever, that the image caption contains any useful content - most of the time they are lengthy hash codes. If these captions were stripped from the og: tags it would help my social media shares look clearer (I rely on shares to bring people to my forum - they’re an important part of my branding).

What is the “raw” content of the actual post?

<sub>One Tree Hill, Honor Oak</sub>

## :tada: Welcome to Lewisham

- The highest number of [parks and green spaces]( of any London borough. 
- London's largest free fireworks [at Blackheath]( each year.

hmmm but why not call the image something sane like: image instead of 58C86A72-CC43-4B36-A8C7-2F360BBA228E ?

when I just pasted an image in I got!



I uploaded the image on my phone. I wouldn’t expect any member of my forum to a) know how to or b) care enough to edit the following:




What’s more, I wouldn’t want [image] appearing in my social shares, either. Or anything that appears in square brackets.

Let me upload an image from my phone

Yep I see the guid in there @sam

(Sam Saffron) #8

Well maybe we should improve that specifically for giant guids, add better handling for file names uploaded from mobile

(Jeff Atwood) #10

Yes we should handle this guid case for mobile, @gerhard can you add this to your list? I assume all iOS devices will benefit from better behavior here.

(Gerhard Schlager) #11

Should we remove the [image] tags from the excerpt used in og:description and twitter:description or is replacing the GUID in images uploaded from iOS enough?

Showing the alt text of images in those descriptions feels like a bad idea most of the time, but I guess there are some usecases where it makes sense to include them.


I’d like for the [image] tags to be removed from excerpts, yes (others may, of course, disagree)

(Gerhard Schlager) #13

OK, the first part is now merged: FEATURE: replace GUID in image name uploaded from iOS (#5370) · discourse/discourse@41e70c4 · GitHub

I’m waiting on feedback for

@codinghorror Do we want to try this out?

(Jeff Atwood) #14

Probably fine, go for it and see what people think.

(Gerhard Schlager) #15

@anon2041049 There shouldn’t be any image tags in the descriptions anymore when you share a topic on Twitter and Facebook. All you need to do is update to latest for this to work.


Many thanks @gerhard. Appreciate the change and the notification.
