#2569 – FB share button and images

Hi

Because we try to autodetect images in the content of the article, not in the full page.
If the auto-detection does not give a good result, you can set a specific image in the URL manager, as described in the documentation.

Lastly, you can try the latest dev version, available from the development versions download area, where the auto-detection has been improved and can include the full page. However, as there are possibly more images found in the page, this might not always get the perfect result, so be sure to check (using the Facebook debugger)and manually correct the autodetection as explained above if needed.

Hi again

Glad to hear that. I will leave this ticket open in case you need to add something. It will automatically close in 2 weeks, if not further comment is made.

Best regards

Thanks and regards

Hi

And that may absolutely be normal, depending on many factors. Please present facts: a list of URLs with detailed information: which page should have which information, which one is missing, what type of content is it (com_content? K2? Virtuemart?...)
And also of course, be sure OG tags are generated by sh404SEF. Is OGP enabled in sh404SEF? some extensions actually generate OG tags themselves for instance.

Hi

Here are my findings so far:

1 - Missing og:description

That's easy: you don't have any description for all those pages, so we cannot create an OG:description tag. Add descriptions to your content, and the OG tag will appear.

2 - Missing og:image tags.

That's the strange one. As I couldn't find anything wrong, I downloaded the latest akeeba backup you did, and restored it on my machine. When I displayed those pages, they all have images and and og:image tag.

I will keep looking, but I want first to hear from you on question #3

3 -

Here missing og:description and og:image mark not first image on display:

That's an interesting one. Here is the source code:

This og:image is NOT added by sh404SEF. The og:tags added by sh404SEF are down below the page, grouped altogether. Do you have another extension adding og tags? did you add them manually in your template or elsewhere?

Hi

A bit more details, sorry about not thinking about it immediately:

og:image mark not first image on display:

That's normal actually. sh404SEF is right and it selects the first valid image. The problem with your other images is that they are too small. Facebook requires that images are 200px x 200px minimum. So we check possible images size, and we do not use the ones that are too small.

On this page for instance, /novosti/boksery-favority-olimpijskogo-turnira-v-rio.html, the first image large enough is http://www.local.web/sandbox/t2569/images/rio_2016/yeleussinov.jpg, it is 225 x 225. The others before it all are below 200 x 200

Rgds

Hi

OK, I understand it now, for the missing images. The problem appears because you are using a lightbox to display some images.

If we look at http://www.xxxx.lv/novosti/rio-boks-denj-2.html, then the image on the right side is actually only a thumbnail: http://www.xxxx.lv/images/rio_2016/stanionis.jpg

It cannot be used, because it's only 275 x 183 pixels (below the required 200 x 200 px).

You also have a link to the full image, but it's a link, not an image, and so we cannot recognize it:

I see 3 options:

- in such cases, you manually enter the image in sh404SEF for this page
- you don't use a lightbox
- you use a larger thumbnail, big enough for Facebook to use

Rgsd

Yes, 200x200 is the minimum image size that facebook will accept. You should consider also whether you actually want to use a lightbox. As your main images are not that large, maybe it's better to just include them in the content, at least on the pages with only image.
On the pages with multiple small images, then having thumbnails is the only option for automatic processing. Still, in this case I would suggest that you manually add an image in the sh404SEF URL manager, for this URL. THe sharing on Facebook and twitter will be much better.
