How do I use a dropdownlist in asp.net to pull up a jpg or bitmap photo from a file, e.g. c:\images\Photo1.jpg; or the photo can be stored in an SQL table
I want to use a dropdownlist in asp.net to select the name of a Product Photo, e.g. Wheel1 and have this display the photo (jpg or bitmap) of the wheel.
For testing purposes the images will be in c:\images\Wheel.jpg etc. These will later be moved to a website folder. I have read it is easier to do it this way than try to store the actual images in SQL but either way is fine. I would like to use VB since I use VBA a great deal in Microsoft Access.
I am great with DB's but a novice at asp.net so please keep it simple.
This is my first time using Experts Exchange. If this has been asked you are welcome to point me to it.
Thank you,

Confused: I am a first time user. I sent a reply to sm394 and it ended up on the screen for beaudetious? Does this matter?

I am confused too. How did you send the reply? There is no such feature at EE.

By "I sent a reply" I meant that I typed the reply into the Comment section as I am doing here and then clicked Submit.
To go back to the original code question. When I select Photo1 from the dropdownlist and then right-click on the Image box on the screen I can see the text "Photo1" but no picture is displayed.
I tried variations on Image1.ImageUrl = "c:\Images\ddltest.Selecte

I worked with the code and ideas you both sent and finally have something that shows the idea is do-able.
Both of you helped me get to this point. Is there a way I can split the points or what's the next step?
Thanks,

The I double-clicked the drop down list and here's the code behind. I am not sure I referenced the c:\images correctly. There are 2 photos in that folder: photo1.jpg and photo2.jpg
Partial Class Lookup
Inherits System.Web.UI.Page
Protected Sub ddltest_SelectedIndexChang
Image1.ImageUrl = "c:\Images\ddltest.Selecte
End Sub
End Class
__________________________
When you "View in Browser" the dropdownlist works and seems to do a post back, but nothing shows up in the image box on the screen. The image box has the small icon in the upper left as though it cannot find anything.
If you can correct any mistakes, I will copy and paste what you send. Thank you,
