showing error while uploading image to sql database

hello,

In my application i need to create a form from which user can upload their pictures into sql database.I am doing it using asp.net with c#. When i run it, it is showing an error. The error is like this.The namespace '' already contains a definition for 'uploadpictest'. When i rename uploadpictest it shows another error which is like this 

1)'ASP.uploadpictest_aspx.GetTypeHashCode()':no suitable method found to override.

2)'ASP.uploadpictest_aspx.ProcessRequest(System.Web.HttpContext)'.no suitable method found to override.

3)'ASP.uploadpictest_aspx' does not implement interface member 'System.Web.IHttpHandler.IsReusable'

What should i do to get rid of these error.

Thanks in advance for any kind of help.
