I'm attempting to validate the width of an image to make sure that it is at least 130px wide before uploading it to the server
Below is how I tried to accomplish this, however, I was still able to upload images that were less than 130px wide without drawing the error as intended

View 1 RepliesI'm creating an ASP.NET control that outputs <object> and <embed> tags. I want the control to have "Height" and "Width" properties, since both of those tags require them. I was also thinking of validating the height and width at runtime. I'm wondering exactly what the valid ranges are so I can be sure I have valid sizes.
These are the types of height and width settings I've seen before. Are these all valid? Where could I find all the accepted formats? Are there any values that are considered invalid, but are used as tricks for cross-browser compatibility?
1px
10%
99.99%
100
I may just go the route of letting the user input whatever they want in these fields, but now I'm curious.

I want if users don't select any image from fileupload control in database it save this image name  'default.jpg'
I 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...

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.

I 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?
I am new to web design so bear with me. I have an .aspx page with a user control at the top that is basically a container for an image. It serves as a banner spanning the entire page. The lower part of the page is a left and right sidebar with a main middle section.
The image is simply some text at the left layered over a background that fades from blue to white, top to bottom. Image size is 90 p. high by 1000 p. wide. How can I get this image to vary width withing the control along with the rest of the page when rendered under different screen resolutions?
