Custom thumbnail using theme_display_thumbnails function
« on: July 15, 2014, 03:34:58 pm »

Looking at the themes.inc file in the includes folder.  I found the display_thumbnails function.  I am curious if this is how to customize the nopic thumbnail picture.  How can it be changed?

Code: [Select]

Re: Custom thumbnail using theme_display_thumbnails function

The easiest way would be to replace the images/thumbs/thumb_nopic.png image with a custom image that has the same filename.

Not recommended (also lost during upgrades):
If you want to change the path or name of the image
edit include/functions.inc.php
Find:
Code: [Select]
$filepathname = 'images/thumbs/thumb_nopic.png';Change to whatever you wish.

Looking at the themes.inc file in the includes folder.
Look at themes/sample/theme.php instead for any theme edits.

I want to tie the nopic thumbnail to the theme so that way I don't have to worry about overriding the file during upgrades.  I have read the documentation, and know not to edit the themes.inc file.  I read in the docs that anything in the themes.inc file can be added to the theme.php file, and anything in the theme.php file overrides how the themes.inc file is set up without effecting upgrades.

Please upgrade first
http://documentation.coppermine-gallery.net/en/upgrading.htm#upgrade_why

Off the top of my head I can't think of an exact way to replace the nopic thumb in a theme.

I read in the docs that anything in the themes.inc file can be added to the theme.php file
Copy from sample/theme.php instead.

From sample/theme.php
I imagine it would have something to do with replacing the line
Code: [Select]
$pic_thumb_url = get_pic_url($CURRENT_PIC_DATA,'thumb');in
Code: [Select]
/******************************************************************************
** Section <<<theme_html_picture>>> - START
******************************************************************************/
with a modified copy of the get_pic_url function.
which you can add to your custom theme.php

Maybe someone will get back to you before I can tomorrow.

Copy the function theme_display_thumbnails from themes/sample/theme.php to your theme's theme.php file, if it doesn't exist.

Find
Code: [Select]
foreach($thumb_list as $thumb) {and below, add
Code: [Select]
        if (strpos($thumb['image'], 'images/thumbs/thumb_nopic.png')) {
            $thumb['image'] = str_replace('images/thumbs/thumb_nopic.png', 'themes/your_theme_name/your_images_folder/your_logo.png', $thumb['image']);
        }
