I have a linq datasource to a repeater control in asp.net.
I want to display images stored in the database tables.

i have a category table and product table among other tables, when i used this code 

<% Eval("CategoryImage")%> .

It displays System.byte[] in the browser and when I used asp image control with Eval(); it give me a usual broken image icon.

could somebody suggest me a way to insert image directly from the mysql database itself via linq datasource..
And how could I format html tags in stack overflow and asp tags too..

Thanks in advance help appreciated...

You can use this function

 public Image byteArrayToImage(byte[] byteArrayIn)
 {
    MemoryStream ms = new MemoryStream(byteArrayIn);
    Image returnImage = Image.FromStream(ms);
    return returnImage;
 }

to convert the byte array to image.

And if you have byte array in Eval("CategoryImage") then you can call this function from Eval also.
As 

<%# byteArrayToImage(Eval("CategoryImage"))%>

Not tested but it should work.
