Pulling images from a database but wrong file name

Question

I am pulling images from a database using a dummy aspx page as it were. The aspx page writes the image data on the response stream and the content type is set to image. This allows me to specify an image ID to the aspx page and it loads the image on the fly. Thats fine for showing the image but the title or name of the image is wrong if the user goes to the file menu and selects save as... The name of the page that loads these images is called Image.aspx and the file save dialog wants to save the file as image_aspx. I do not want to force my users to have to enter a file name here. Is there a way I can changed the title file name or whatever so that the browser sees the name as lets say image1.jpg?

Instead of using a page I am using a http handler but this only resolves having a dummy page laying around. You are write I can add a dowloadlink and set attachment to solve the problem. In all other cases I am doing a Content-Disposition inline so that the media is shown in the browser. The filename hint works for images but not for PDFs. If you have adobe acrobat installed then the pdf inlines into the browser fine but if you click the save button in the acrobat control it wants to save the file as File.PDF based on the dummy file name the handler responds to which is File.aspx. I am not sure it its an oversight on adobe or if they can even obtain the filename hint when they open up their control but they are not using it. Thanks for the response I have tried about a hundred different incarnations to get this to work.

It is not in your hands. If the pages filename is page.aspx (although it is an image) most browsers use the filename as an estimate. However you could provide a donwload image link and you could give the browser a hint to use different filename when saving. Response.AddHeader(Content-Disposition attachment; filename=image.jpg); Hmm I haven't tried if this even works in your case(without different download link) have a try and tell me!
