How do I effectively split my site into several small parts for upload. I have graphics and sign design site with thousands of template images that open to my design generator.

I have to upload thousands of images (and I do not want them to be blurry or too small).

When I have tried to upload a part of my site (deleting pages that are unchanged) upon the upload my xara web designer deletes all pages or items from my site that are not on the current upload.

How do I bypass this so I can upload only what my system can handle at any time and not have the system delete items that are OK (and not in the new upload or publishing).
