First and foremost, I want to express my sincere gratitude for producing a fine SMF media gallery product. While I may post about issues or shortcomings, I really do appreciate the work and like the product. We've tried Menalto's Gallery (with Oldiesman bridge) and Jan Sorgallo's 4images products. None have integrated or performed better than SMF Gallery Pro.
We've been using the keyword feature of SMF Gallery Pro. We also display the Tag Cloud on the gallery main page. If a user clicks one of the tags there, they get a search result for that keyword. Everything's great at that point. But if they click any image, the next/previous links above are not for the next/previous images in the search result set. They are the next/previous images adjacent to the selected image in the gallery in which that image is located.
