Wordpress gallery plugin

Hi, we need a new gallery plugin for a wordpress website. The plugin CAN be based on some existing one (for exampl Nextgen Gallery or something like that), but should include all the functionality we need. 1) Pictures should be divided into categories. 2) Every picture should include: Category - Should be able to set categories for pictures. Should be possible to filter by categories in the front end. Tags - Should be able to add multiple tags. In the front end it should be possible to filter by tags. Picture name - Just a name of the picture, it will be names of the buildings. Company name - Name of the company that owns the building. Should be possible to press on a company name and see all images from this company. Author - Name of the author of the image. Should be possible to click on the name and see all photos of the author. Download button - Should be possible to add a file (full sized image) to the image. We will upload optimized pictures to the gallery - every picture will be about 300kb, but we want the users to be able to download the FULL SIZED version of this image, i might be jpeg, png, tiff or raw format (depends on the image). 3) In front end it should be possible to filter images by Tags and Categories. When clicking on the image, you should see Picture name, Company name, Author, Category, Tags and Downlaod button. I've attached screenshots of the front end. This is how it should look. The underlined texts should be clickable, to filter by author, company name, category or tags. Let me know if you have any questions.
