The things that affect the quality of your photos are how they are processed and how the browser views them. The hosting site has no influence on the photo unless it reprocesses the photo.
As far as I know the gallery here does not reprocess the photos.
What I would recommend is to manage your photos on your PC. Use a program like Google Picasa to sort and manage your photos. When you want to put them on-line, you select the ones you want, then export them to a temporary directory - say on your desktop - resizing them appropriately for the site. Then upload them. Finally get rid of any temporary directory.
My camera takes 18MP photos and generally I shoot them at 2592 x 1728 pixels. For Facebook or blogs, I resize photos to 1024 pixels wide then upload them. For the forum I resize from 800 to about 900 pixels wide before uploading. I like to control the final quality of the photos so I resize myself using the most appropriate method. Saving the forum images for the web at about 60% compression gives a good result and still allows for a fast download.
