Updates to Artist Gallery Website

We have a site which has been built been another RAC programmer and now have a problem. The coder seems to have disappeared and we cannot get in contact with him for any updates or fixes to the site. ### Overview The site is a gallery-based website driven by a backend database. Member use the site to display and sell their artistic work. The artists, once registered, have access to an upload area where they can upload pictures of their artwork which will then be displayed on their page. Art is not be sold directly from the site but the potential buyer is put in contact with the artist via the site, either by internal email or by mail relay. The artist pays a fee to display his art on the site, the fee being determined by the number of images they want to display. This all is currently managed by Paypal subscriptions. There are two options for each payment plan - monthly and yearly payments. These are preceded by a 3 month trial; after the 3 months the user is set onto the selected package and is charged through PayPal at the appropriate price. ### Problems We have discovered a few minor issues, one which was discovered after the first few customers finished their 3 month trial. 1 - The Subscription Payments from the PayPal IPN system is set up incorrectly. I believe the monthly/yearly payments simply need to be reversed for when an artist finishes their 3 month trial. For instance, a user who comes off a trial is currently set to pay £110 per month or £10 per year - these figures should be the other way around! 2 - The sites' global 'Sold' gallery is not showing all Sold Art as it should. Each Artist has a sold page where their sold items are displayed. There is then a site-wide 'Sold Gallery' which should show all items from all artists that sold work. This is currently only showing a small sample. ### Addition 1 - We would like for viewers to be able to click through the galleries without the need to view the thumbnail list again. By adding a next & previous button this would improve usability when viewing the full-size photos.
