Web Forms :: .NET Page With Lot Of Images?
Jun 16, 2010
I am creating a Web page where lot of images will involve. it's like admin uploding the products and the users can search and see the products. so, for this i have stored the image in the database itself in a column with varbinary(MAX) datatype. is this the right way/ best way to do it or storing the image in the Server and storing the server path in the databse will be the best solution for this or do we have any other solution for this kind of website.

I've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.

I have some code that successfully traps an error 404 and diverts to an appropriate page. However, I have a problem with certain types of error. My code will trap the scenario where a user types, e.g.,
www.mysite.com/indecks.aspx where no such page exists. However, if the user types something along the lines
www.mysite.com/index.aspx/nonsensetext where index.aspx is a valid page, the page load event for index.aspx is triggered. However the page is rendered incorrectly because, I think, it is failing to find the images and CSS file associated with the page - perhaps because it is looking at the wrong path.
I expect that I can trap this by examining, for example, Request.URL.OriginalString and, if I detect garbage, I could re-direct to the same page "more cleanly" (i.e. without the junk on the end of the URL). However I'm a bit concerned that this is happening at all. Shouldn't this be treated as a 404 error?

In my web application I have a separate folder for Images and MasterPages and I am using forms authentication. Thus if I will not allow anonymous access for Images folder the login page will not be able to show any image.
guide me if this is what we should be doing or is there any other way to handle the scenario. Also, let me know is there any drawback of this technique.

I have a project I'm getting ready to start and I want to see if anyone out there has any good examples or suggestions on how I would handle processing images. My company has about 10,000 images orgainzed in folders which I am planning on pulling into SQL Server. What I want to do is develop a web page where the end-user can select a folder which would then be scanned for photo / image files.
Each image file found would then be displayed in a column in a web page and the end-user would then select certain options for each image. Options such as where the photo should get stored in the SQL Server Database. My wish is to store the images in a number of SQL Server Tables in a field type of IMAGE. I'm using C# as my programming language.

I have a few css files, javascript files and images referenced in my master page. When I do a "View Source" of the pages that use this master page, I can see that the css files are showing correct paths but javascripts and images don't. I tried using "~" in path but nothing worked so I used relative paths.
If I have a path for css file as "../../css/blah.css" and a page that is in sub-folder uses this master page, it correctly shows the path as "../../../css/blah.css". But the images and javascript paths continue to show the original path (hence broken images, javascript errors, ...).
A javascript source listed as src="../../scripts/blah.js" continues to show as "../../scripts/blah.js" instead of "../../../scripts/blah.js". Same thing with images. I did try "~/scripts/blah.js" and "~/images/blah.gif" but still can't find it.

When the screen resolution changes then the page is getting scrollbars which i do not want as this is the home page of website.
I want the web page to adjust the images size and other page contents according to the client's screen resolution.

I am using forms authentication, and for some reason it shuts off my images. I have tried putting them in the same directoy, and still nothing.
If I turn off forms authentication, they come back alive so I know my urls are correct.
