Wordpress Theme Fixes

Hello, My website ([login to view URL]) needs the following fixes: - Place search field in line with the rest of the menu items - Remove menue item "filter" - Remove grey space between menu bar and photos - Disable "fading out" effect when hovering mouse across pictures - Display 24 images on front page, not only 20 (increase theme limit) - When clicking on an image, please fix the design elements according to the attached "wallpaper" image - Fix the error: When somebody has an "Adblocker" installed, they can't download any wallpaper, because it blocks the disclaimer box. How can it be prevented? - If the disclaimer box can be made possible even with adblockers installed, please adjust the design so that it matches the overall design of the website. (Grey, transparent, dark, flat) - Fix the error: When clicking on an image on the front page, the according wallpaper slides in from the right. When I hit the download button, no disclaimer box appears. Only when accessing the wallpaper via the search function, the disclaimer box appears and lets me download the wallpaper.
