I tried to do something recently but unfortunately I realized that slideshows do not appear in the Clan DSC ='|

What is the reason for this?is this is a problem or was removed?

Afaik its just broken. It will show on your clan threads just not the clan page.
I am p sure its supposed to work it just doesn't.
Its kind of like how with signatures if you have enough space you can adda slideshow.
When you preview it, the slideshow works. But when you upload the signature the slideshow stops working.

They only work on OP posts.

mm okay, thanks
