Looking for ASP.NET web toolkit/solution for data bindable images to SQL Server 2005

    We are looking either an ASP.NET web toolkit or someone who can assist us for the handling images within a SQL Server database and displaying them. We do not need editing, conversion, PDF. Does anyone know of a ASP.NET DLL toolkit that will do this. More on the requirements below. We would like to create a web application in ASP.NET for doing web based training for State employees. The concept is to have a set of Courseware pages that the creators of the training content can insert images and text into. Then the students (State employees) will be able to view the images and text from a web browser and takes the courses. The images for the training content are going to be clipboarded using a very popular and State supported package called SnagIt from TechSmith. From what we understand the native clipboard format for SnagIt is PNG. We do not want to save the snag’ed images to files. The SnagIt product has a wonderful virtual clipboard that eliminates all of the issues with saving images to files and remembering the names later. The images that are captured using SnagIt and clipboarded will be stored in a SQL Server 2005 database in either an (Image) or (VarByte) data typed column. We do not want to use saved image files with links to the files defined in the SQL Server database and then manage the transfer of the images files between the courseware creator and the web server. Our goal is to simplify the courseware creation using the supported environment and tools (SnagIt). Our research indicates that you can not write ASP.NET web code that uses the windows clipboard because of security concerns. Many Google’d pages indicate this can only be done with a 3rd party DLL or Active-X components. The State does not allow Active-X but will allow a DLL within the web application. We have created a test platform with a SQL Server 2005 database and the table with the (Image) data type column in it. We can Snag images and clipboard them into the image column using an MSAccess simple form linked to the database. We can then page through the images using the MSAccess form. We are trying to avoid having to use MSAccess for the courseware development part of this application. We really want the entire solution to be web-based. Even with the MSAccess form and saved images in the SQL Server 2005 database we can not get a web page to just display the images from the database. We have a number of posting in the ASP.NET forum in an effort to resolve this. We have tried HTTP Handler, byte arrays, memory streams, etc to no avail. We think the issue has to do with us clipboarding the image from SnagIt and how it’s saved using MSAccess. Again we want to avoid any MSAccess in this solution. We have started research on 3rd party toolkits but so far all of them are for heavy duty image processing, editing, etc. We need a simple data bindable image control for SQL Server 2005.
