ckeditor and fckeditor plugin expert

I currently use fckeditor for my members on my website. The members I have create webpages for their website with me with my online tools. The custom plugins that I have for fckeditor do not work in windows 8 metro. I send people to windows 8 desktop. I would like to update the editor so it works in all browsers AND windows 8 metro. The custom plugin I have now, pulls images from a specific folder (specified by php echoing from the database). Then displays those photos in a pop up window, allows the user to choose from the photos and add them to their page. It also gives them the option to choose "thumbnail to full size" as then then upload the photo (on a different page) it creates a full size and a thumbnail version of the photo so they can create thumbnails liking to the full size image. Let me know if you can make this work in the new ckeditor. I need it look and act just like my current fck editor so my members do not have to relearn adding photos to their page and editing their.
