Phoca gallery tricks

Here's a linux command line solution to remove all your phoca thumbnails so the system will generate them again:

cd /home/your_joomla_folder/images/phocagallery

find  -name "*phoca_thumb*" -print0|xargs -0 rm

And here's another Phoca gallery trick for global watermark files(i.e you will have global watermark files instead of having to copy watermark-large.png and watermark-medium.png into all gallery subfolders):

This modification will watermark all files in all categories and subcategories subfolders using global watermark files placed in [your joomla root]/images/phocagallery.

Watermark files should be named watermark-large.png and watermark-medium.png, and you should save them as RGB PNG images with transparency.

You have to edit phocagallery.php in administrator/components/phocagallery/helpers

add this line

$path=JPATH_ROOT.DS.'images'.DS.'phocagallery';

before 

 // Which Watermark will be used 

,then a little bit below replace

$fileWatermark    = str_replace($fileName, 'watermark-medium.png', $file_in);

with

$fileWatermark    = $path.DS.'watermark-medium.png';

then 

$fileWatermark    = str_replace($fileName, 'watermark-large.png', $file_in);

with

$fileWatermark    = $path.DS.'watermark-large.png';

the code should look like this now:

// TMJ MOD
// global watermark file instead of per-gallery folder
$path=JPATH_ROOT.DS.'images'.DS.'phocagallery';
// Which Watermark will be used
if ($thumbnailMedium) {
    // $fileWatermark    = str_replace($fileName, 'watermark-medium.png', $file_in);
    $fileWatermark    = $path.DS.'watermark-medium.png';
} else if ($thumbnailLarge) {
    // $fileWatermark    = str_replace($fileName, 'watermark-large.png', $file_in);
    $fileWatermark    = $path.DS.'watermark-large.png';
