I use AsyncFileUpload to upload images. It works fine.In this code I check so the size isn´t bigger than 1 MB and that it is a .jpg file.What I also will need to check is that the Width isn´t bigger than 100 and the height isn´t bigger than 200.I wonder how that could be possible to do in the code.

View 3 RepliesI know there's been a lot of dicussion about removing inline styles that asp.Image control renders by default. I have applyed soultion mentionedhere. But I am facing another problem with this control. If I set Width and Haigth attributes on Image control and the result HTML is:
Source code:
<asp:Image ImageUrl="~/style/images/image_big.png" CssClass="someclass" runat="server" AlternateText="Image alt" Width="179" Height="53"/>
Result code:
<img src="style/images/image_big.png" class="someclass" alt="Image alt" style="height:53px;width:179px;" />
What I would like to have is separate Width and Height rendered outside style attribute. Like when having server HTML control. And let's say that I cannot subsitute asp.net image control with HTML server control.
Is there a way to somehow render Width and Height for asp.Image separatly?

View 1 RepliesI want my users to upload their photos to my website. I am using fileupload for this. I have jquery to crop the image to desired size ( according to user).What I am doing is this, when a user uploads a photo, I use the uploaded image's address as ImageUrl , and the user gets its pic dynamically as soon as he uploads it.And then with the help of jquery , user can crop it to dimension of his/her choice. Finally, I get a cropped and smaller image. [:)]But the real problem is this, if a user uploads a picture of greater dimensions ( e.g. 1600x1200) , image covers up all the screen, so I want a method so that the uploaded image get restricted to a fixed height and width (say 500x5500) before it is available for cropping to the user.I have tried .......,Image's Width=500, Height = 500 ( using asp:image ) and attribute.add.style("width:500;height:500); ( using html img ) in code behind after uploading image . The image first appears in 500x500 dimension but immediately changes to its original dimension...

View 8 RepliesIn my Web page,I have a Div section with height=302PX and width=302PX.
In another page,I had a File Upload control. When we will upload the image,then the image will be displayed in that Div section.
1.When the image is large,it should be re-size and display in that particular Div section completely.
  For Eg:The image size like 350PX*350PX and 1024PX*1024PX, it should be re-size to Div Section size has 302PX*302PX.
2.When the image is Small,it shouldn't be re-size and display in that particular Div section completely.
  For Eg:The image size like 50PX*50PX,100PX*100PX and 302PX*302PX ,it shouldn't be re-size and display in that Div section.
  For Eg:The image size like 15PX*15PX these will appear very small.But When uploading the file these images also should displayed completely with as it is  in that  Div section.But the image will displayed neatly.
3.If there are any tools for these type of conditions using ASP.Net.

I am trying to set the width and height of images in a datalist in the codebehind.
The plan is to do something more complex than this based on the width/height, so setting width and height in the aspx file to 50% is not an option.
For some reason I always get 0 for width and height. Image1.ImageUrl is what i would expect though. Image is the System.Web.UI.Webcontrols.Image, not a System.Drawing.Image.

I am retrieving an image from SQL Server to display on a new page in my ASP.NET 4.0 application using this method (one of my posts):

I am then displaying the image in a new window using this method: (one of my posts):
How to display an image in a new window
What I am trying to do is get the height and width of the image so that the new window is created with the same height and width as the stored image. I guess there are two ways of doing this:
Create a height and width column in my database and store the values when the image is inserted into the database Retrieve the image from the database and calculate somehow the height and width just before displaying it and then resize the browser window to the right size.
I already have over 150 images in the database so that makes option 1 difficult because I would have to go back over my db and calculate height and width for images that are already in the db. Therefore I would prefer to use option 2, or maybe there's another option? How would I go about doing this?
