Images - Store In A Database Or File System?
Jun 19, 2007
I have recently designed and built my first database using SQL server 2005 express. I have included an image (BLOB) column in one of the database tables. This is a bad idea according to some experts, and some say it is OK!
I am currently carrying out a trial with just 3 pictures via Visual Basic 2005 express forms, and there is no problem so far as the images are displayed for each record. But I anticipate between 300 - 1000 images for the table, and this could pose real problems for SQL server 2005 express and Visual Basic 2005 express, I guess.
I have just been reading that the cost of storing large images in the database is too high! I have also read it's better to store images (BLOB) into the file system because it is cheaper to store them no matter how many there are.
But the question is how I can reference an image in this path: C:PictureProductGrocery 0052745.jpg in the database table, so that when I select a record Visual Basic 2005 forms the image is displayed accordingly, similar as when stored directly in the database table? Your help very much appreciated.

I am looking for some microsoft recommendation on storing images in SQL Server Vs File System. Here is what our requirement is.
Currently we are using SQL Server 2000 with a VB6(COM+) & ASP front end. Our architecture involves Log Shipping & Replication. We use log shipping for our DR site and Replication to replicate to Datawarehouse & DB2 enviornment. I have been trying to research this topic and have come up with opinion favoring both sides mostly file system but nobody seems to point any Microsoft recommendation.
With our application we are looking for Transactions, backups, Log shipping & replication with these images. I have read MS implementation of TerraServer and there they recommend storing them in SQL Server if above is required. (https://www.microsoft.com/technet/prodtechnol/sql/2000/reskit/part3/c1161.mspx?mfr=true)
Can somebody please point me to some Microsoft recommendation and what does SQL Server 2005 offers in this aspect.
Thanks

Images, PDFs, word documents, etc..., will it affect the performance of my sql if I stored them in it as blob objects? Or it's better to use the filesystem instead and just store file paths in my sql?
thanks in advance

Can you store images in a database or in a table, or do you have to only store the image path/name in the database while the image is in another folder? IF anyone knows, please share with me. Thanks.

I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?
Imports System.Drawing
Imports System.IO
Public Sub InsertImage(ByVal pFilename As String)
Try
Dim lImage As Image
Dim lBA() As Byte

If you serialize the image into a string ? If you want to save a byte array to a string, do you have to use a base64 encoded string ?

hi guys, are there any official or some sort of documents to talk about the advantages and disadvantages of storing image in the SQL's Image datatype field or storing the pointer to the image file? i have lots of static images (no more than 1MB each) that requires little updating and i need to retrieve them constantly. i am really struggled here on which method i should store the images: to store the images as Image datatype in SQL or save them as files and store the paths to the files. i would like to know, in my case, would there be any performance and efficient difference on using either method?
naturally, i'd think the 1st method seems like a better solution. it's easier to back up and it protects integrity. But at the same time, i am not sure if the constant inserting and retrieving of images will affect the performance? also, i want to share the images and may create a ticker thing (using JavaScript) to display the images on the web page randomly and it seems like the 2nd method is easier to program. if you were me, which method would you use and why? thanks!

I have a client who wants to be able to upload images to his website for his customers to access. It will probably max out at 100 images a month...so not a huge amount of data. I am using asp.net 2.0 and SQL Server 2005.
Does anyone have thoughts or opinions on why I should or should not take this approach?

I have a web server running fine together with an sql 2005 db. I use asp as my web server programming language and want to be able to display images that are stored in the database.
My question of course is how do I put images, for example an image called "image1.gif" into the database?
After having stored the images in the db, I guess that the are displayed on my web pages the same way as all text information (by writing something like <%=rs("image_column")%> ).... Anyway first I need help with how to store imgs in the database...

Hi, for my photo album database I'm trying to decide whether to store the actual photos as images in the db or whether to leave them in file directories with just the path & filename in the db. As a beginner in this field I don't know how either of these options compare (e.g. in terms of performance, complexity, flexibility and maintainablity) so any advice on the pros and cons of each would be appreciated.

Hello all,
I've been asked to build a .net web application, where users will be able to upload, search and view images. There will probably be about 2000 - 10000 users who will upload and view photos each day.
Each image that is uploaded, is saved as a thumbnail, a small image, and the original. So considering the possible amount of data being uploaded, stored, searched for and viewed, whats the best way to store the images? Database or File system? Whats would be the fastest option for a web application? Should I even be looking at a different solution?
cheers!

Hi. I am currently building a blog application, and I need some advice... I have the post title, post date, post by, etc stored in a database table, however I was wondering whether I should store the actual post content in the database as well or in a text file. For example, if the posts get really long would it slow down database performance or would there not be much of a difference? Furthermore, if I wanted to keep the posts private, a text file would not be ideal as it can be accessed easily by surfers... What do you recommend?Thanks a lot

I have a well-structured but also very large binary data-set that is generated by a C++ application every five minutes. The data needs to be accessed by SQL applications. Since data is generated every five minutes, performance is key, both for write and read. The data set is about 500MB.If data is written to the file system, the write performance doesn't involve SQL server. For reading it, I have a CLR to read the portions of the data that I need based on offset and length. That works and is very fast. The problem is that data is stored in the file system, so it is not self-contained within the database.
A second option that I haven't explored yet, is to write the data into a table as VARBINARY(MAX). I would read the data using SUBSTRING with appropriate offset and length. Performance of SQL write/read of binary data of this size, and whether there is a third option I haven't thought off. I'm using SQL Server 2014.
