Random pictures

<< < (30/31) > >>

kangarooms:
Ich habe versucht es in meine details.html ein zubauen aber es wird mir nichts angezeigt  :cry:

kann mir wer helfen?

praveen:
Is it possible to show random images from subcategories too?

I have 3 main categories with lots of sub categories.

The main categories do not have any images.  So can the random images be shown from the sub categories?

wallward:
thank you V@no
how to exclude some categories?
for example 3 and 16

Loda:
try this in the code:
.....
 WHERE i.image_active = 1 AND c.cat_id = i.cat_id AND i.cat_id NOT IN (3,16) AND i.cat_id NOT IN (".get_auth_cat_sql("auth_viewcat").")

Geezer:
