Another problem is that you have to create your own images/phocagallery folder that isn't off the default images/stories so other programs cant find your images to display. Why cant you go with the defaults?
Fix those niggles and you'd have me very happy.
Phoca Gallery doesn't create copy of original images, there are three thumbnail types:
- small - displayed in Categories View, in administration
- medium - displayed in Category View, in administration
- large - displayed in Detail View, in Switch/Swap function, in Overlib
Large thumbnails are important, because e.g. users upload images with 3072x2304 or 2816x2112 and other similar sizes. Such size cannot be displayed in browser (on common displays) so e.g. size of large thumbnail, which is 640x480, is needful.
If you will add watermark, it is added on medium and large thumbnails, there is no duplication, no doubling the memory usage
Phoca Gallery images are stored in images folder, which you can access by other programs, just set the path in Global configuration in Joomla! - the parameter is called Path to Image Folder
