changing the size of the gallery images takes a fair bit.
in the admin/common/properties.php the following code sets the sizes of the images to create when an image is uploaded to a gallery:
$GLOBALS['resize_proportional'] = array(
array('w' => 1024, 'h' => 768, 'watermark' => true),
array('w' => 782, 'h' => 481, 'watermark' => true),
array('w' => 163, 'h' => 92)
);
$GLOBALS['resize_cropped'] = array(
array('w' => 62, 'h' => 62),
array('w' => 132, 'h' => 140),
array('w' => 102, 'h' => 102),
array('w' => 42, 'h' => 42),
array('w' => 782, 'h' => 481, 'watermark' => true),
array('w' => 995, 'h' => 260, 'watermark' => true)
);
in the galleries folder, the is a subfolder for each gallery type. in each subfolder is an index.php file that generates the gallery. For example, the Ribbon Light box Power store gallery is generated by the gallery/ribbon_lightbox_powerstore/index.php file.
in the index file, there will be a line similar to this:
$gallery = get_gallery(get_mediarss_url('gallery=' . $pg_id . '&thumb=62c&full=782p'));
that sets the image sizes to use. in this case, the thumbnails use the 62c image size defined in the cropped array:
array('w' => 62, 'h' => 62),
and the large images use the 782p image size defined in the proportional array:
array('w' => 782, 'h' => 481, 'watermark' => true),
you can edit the index file to set it to use a different size for the large images:
change:
&full=782p
to:
&full=1024p
for example.
you can also edit the properties file to define a new image size. if you define a new image size, you will need to edit the water mark to have the images regenerated.
