Store And Retrieve Images From File System Instead Of Database
Mar 17, 2010
I need a place to store images. My first thought was to use the database, but many seems to recommend using the filesystem. This seems to fit my case, but how do I implement it?
The filenames need to be unique, how to do that. Should I use a guid?
How to retrieve the files, should I go directly to the database using the filename, make a aspx page and passing either filename or primary key as a querystring and then read the file.
What about client side caching, is that enabled when using a page like image.aspx?id=123 ?
How do I delete the files, when the associated record is deleted?
Is it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...
i have a web page in asp.net.vb code and sql database.
the persons number is called PNUMB and i have stored all photos of persons in a folder with the persons number (PNUMB) as their file name. when i search for a PNUMB i want to display the photo of the persons whose dtata is displayed. how i sit possible
Which is the better alternative when allowing file uploads on a page (through a Gridview populated by a coded DataSet)? Store the image itself in the database or to store only the path name to the saved file in file system. If it matters, I do not expect to have more than a few dozen images stored in the database at any given time.
Its related to datatable in gridview store in session and then session retrive and store to database. basically i am using gridview here creating new row for button click and these row adding untill user's last entry then submit all these entry to database. so i want to use session variable to store this data temporarily and after final entry user click on submit button and all data shold be save in db.

1.store them in the file system of web server and put the url in the table? 2.store them as type "image"? 3.store them as varbinary(max) BLOB? 4.store them as filestream data?
I am working on a project (asp.net web application) that takes files from users, stores them and retrieves or shows them back to the user when needed. I am saving files on my file system (drive). When I save images and refer to them in iframes, images are being displayed in iframes. But when I save .html file and refer it in an iframe it is not displaying the html file. I want to store a .html file on my file system using file upload and store on my local drive, display it in an iframe.

ImageID, AlbumID and ImagePath.I want to retrieve the photo and display out at my index page inside a gridview which will display the photos that recent users uploaded.My friend suggested the Eval way, but i have no idea how to do it.
in ImageAddress field i have stored physically address of my images and each project has more than one image. how could i show all images that belongs to a project in a GridView?
My problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
I have one folder which contains the jpg images. That images i want to store binary format into sql server database. And finally that images binding in the DataGrid.
