I tried searching the web and no help. i have a asp:image map control. I want to be able to code it all from the code behind. I got everything to work except for the hotspot. What my code does it randomly pick an image to display everytime the page is reloaded. But I also want to update my URL. I just don't know how to make my hotspot work with my imagemap in the code behind. This is what I have so far:

I've read some articles about how to customize the look and feel of CreateUserWizard but none of them showed me if I can display my error messages somewhere else in the layout. Currently, they appear right above the register button. I'd like to display them next to the table so that there's plenty of space.

I'm using varbinarymax.....IN SQL gridview image and setting the nullimage value doesn't this problem.. I'm looking for code that can make this lil miracle happen
& it doesn't really matter which way , whether the code says if image null then display this image from ~/Images/thispic.jpg or if i1 display this image from ~/Images/thispic.jpg for a little bit more insight into this I'm creating a legend for the database and the null has been used for displaying one pic so i'm after the 1 or visa versa to display another image.... and i'm not trying to upload pics to 1000 plus documents, and when i came at it from a sql angle tying 5 tables together the parent table ended up not sending the proper return. is this even possible or am i ahead of visual studio
I found this code on another site and it works great for resizing the image and keeping the quality. What I want to do at the end is check the height of the image and if it exceeds a certain number, just change the size of the image. Not resize it but just cut off part of the bottom to be a certain size.
Code:
Dim image As System.Drawing.Image = System.Drawing.Image.FromFile(src)
Dim srcWidth As Integer = image.Width
Dim srcHeight As Integer = image.Height
Dim thumbHeight As Integer = (srcHeight / srcWidth) * thumbWidth
Dim bmp As New Drawing.Bitmap(thumbWidth, thumbHeight)

I have generated a barcode image through my web application and then gets it print out but that printed barcode image is not recognized by a laser barcode scanner ,below is the code which I used for generating barcode image
int BarCodeFontSize = Convert.ToInt32(ConfigurationManager.AppSettings["barCodeFontSize"]);
in my source view of my web page I am using some images. Right now I use the code:
HTML Code:
<img class="smallIcon" src="skins/itsoft-images/small-icon.png" alt="Small Icon" width="20px" height="20px" />
I use this image many times in my pages, as well as other images. I don't want to use a path like this because if I ever change the location of the images, I will have to update a hundred pages.I would like to place the path to the image in my web.config file, and have the code load from there. I'm use to doing it in PHP but I can't figure it out in .Net.
Something like:
HTML Code:
<img class="smallIcon" src="<%@ ICON_FILE_DIR %>" alt="Small Icon" width="20px" height="20px" />
Is that even possible?

I am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.
I have an page with upload the image by fileupload to the database the display the list of all the images in the same page by grid view,
I am not able to view the images but the rest of details like imageid, name are displayed here the code like have an look into this and let me know where i went wrong its urgent...

I created an image button in my header template. When clicked, it calls the Sorting method. When I change the image url in code behind, it does not render. By setting a break point, I can see the property being updated, but I assume it is getting overridden by the default I set in the HTML page.
Code:
<HeaderTemplate>
<span>Claim Id</span>

var sortButton = (ImageButton)sender;
// parse new sort
var newField = sortButton.ToolTip;
// parse existing sort
var existingSortArgs = this.ClaimSort.Split(' ')
