Need experienced Flash developer to help update existing Flash site

I have an existing Flash site that was built by another freelancer several years ago and I need to update it but unfortunately the original provider is no longer available. The front-end of my website is in Flash, and is powered by a .xml file which contains all the content for the site. The site also includes a photo gallery, and there is an option in my XML file to set the size of the image thumbnails. The original thumbnail size was 120 x 120 pixels, but since I now have lots of photos, I want to make the thumbnails smaller so that I can fit more on the screen. The problem is that the way my site is currently set up, there is a gap between the menu and the first row of thumbnails above the menu after adjusting the thumbnail size. I need someone to update my Flash site (I can provide the web files as well as the .fla I received from original provider) so that the thumbnails will behave correctly no matter what the size of the thumbnails is. There is also another small change I would like made to this site which involves moving the location of the "Back" button from within the gallery pages. I will provide the URL to the site for freelancers with good bids so that you can preview what I mean/need. This is a SIMPLE project for anyone who is experienced in Flash. I will not pay high price for this project since I know what's involved in making these changes - I just cannot make them myself. I will award this project to the freelancer with the highest reputation and lowest bid. Payment will be made via Freelancer escrow system. Payment will be released upon completion of the project when I am satisfied that it has been completed to my specifications. If you have any questions, please send me a PM.
