I need to create a database in SQL2005 on a webserver (manually (not in code)), have registered users upload an image to a webserver not overwriting if the filename already exists but to append if required Weekly, I wish to review the uploaded images in the uploaded folder, create a user & add the image(s) into the database programmatically for all users to be able to search / When the image(s) are in the database & are searched or shown (ex: profile shown with all those details/pics displayed but before displaying the pics on the form to watermark them. However, a profile could have 1 pick or it could have 20. I would like to have for example 4 pics being shown then the user to click next till the end of the recordset. Then do the same for another profile. Uploading the file is fine but not to append if exists then maybe I should have an upload date as the filename (haven't decided)
