Photos from one category on external page

[anoleimage]

I'm sorry if this has been covered, but I couldn't find it with the searches I tried:

I would like to have a small group of thumbnails on a site homepage that would be pulled from one category in 4images.  Kind of like a "featured thumbs" kind of thing.  I've seen mods in this forum for new images, etc. on outside pages, but I'm not well versed enough in PHP to alter those scripts.  Any help would be greatly appreciated.

If anyone is familiar with OpenRealty, this would be like Al Smith's "Featured off-site" plug-in...

Thanks in advance for any input!

Nobody?  K'mon:  Can any PHP wiz pull thumbs for a category to be displayed on another (external to $images) part of the site?  I know somebody can do this.

Thanks for any blind alley you can send me down...

Hello;
please learn to be patient. People use to sleep, sometimes, here.
Don't know about OpenRealty, sorry.

But try this: [MOD] new images on your homepage (external)

and complete with this: {new_images} from specific category to match with your favourite category.
Or else, that's the way I should do it:

3 new files have to be created:

• new_images.php (at the gallery root, where index.php is)
• templates/your_template/new_images.html
• templates/your_template/thumbnail_bit_extern.html

1 file has to be modified:

• includes/functions.php

First, lest us create the file "new_images.php", just copying a part of the file "index.php". The code should be:

Code: [Select]

//--End external thumbnails----------------------------

Then, the external site that desires to show your thumbnails has to include one of these two links in its page code:
PHP:

<?php include ('http://path/to/your/gallery/new_images.php') ?>

or HTML:

<iframe src="http://path/to/your/gallery/new_images.php" width="500" height="300" scrolling="no" frameborder="0" name="new_images" align="center"></iframe>

(Width and hight are just an example. Adapt it as you prefer.)


You may modify this, in "new_images.php":

Code: [Select]

$num_new_images = 12;
$config['image_cells'] = 4;to change the number of thumbails shown (12, here), and the number of thumbnails in each row (4, here).

Don't forget to change this:

Code: [Select]

        WHERE i.image_active = 1 AND c.cat_id = i.cat_id AND i.cat_id IN (1, 2, 3)to specify which category's thumbnails you desire to show.
Well, I hope I did not forget anything essential.
Feel free to ask any help.
Anyone here can help you as soon as he is awake...
