Uploading And Resizing Pic

My client wants me to add a functionality which would enable him upload and resize the pictures. His server is having ASPUPLOAD and e-kov components intalled. Also he doesn't want to write files to the disk and save only to memory.

I can use ASPUPLOAD's functionality to save files in memory or save files in the database. My question is how can I access a file so that I can resize the image using e-kov software. And when using 'upload.save' only, without path, it saves the file virtualy but where does the file and how to access it.
