Cascade Record & Image Deletes
This tutorial is the third of a three part series on image delete options. Unlike the other two tutorials we will be not working with George Petrov's Pure ASP upload behavior on this page. Instead we will look at how to remove related records and the images associated with them when deleting a master record. By controlling orphaned records we keep the database tables clean and our applications run faster with fewer resources consumed. It only makes sense to remove images associated with the deleted records as well, again conserving server resources. Read MoreJavaScript

Multiple Image Delete & Remove Options for Pure ASP Upload
This tutorial is the second of a three part series on image delete options using George Petrov's Pure ASP upload. The first shows how to handle image delete and remove options on an update form with a single image. This tutorial looks at update forms with multiple image fields. Having more than one image imposes limitations on image remove and delete options, but with a bit of imaginative thinking and a little hand coding we'll see that we can provide users with a full array of image handling options.
