Great extension. However, there is what for some could be considered a major flaw limiting its use (and which can probably be easily remedied): Pictures in the Phoca gallery cannot be Alt-tagged. This limits the value of this extension for people preoccupied with search engine optimization. Search engines use the alt tags when crawling sites for images. Other users of the system have reported the problem at the Phoca Forum but we have not seen a resolution yet. Apparently at this point there is some customization required to resolve the problem but not much information available on the procedure. Most probably this will be resolved soon. This should not detract from an otherwise extraordinary work.
