how can i store images in database? and how can i call them back?
please give me in detail.

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?
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.
View 2 Replies View RelatedI 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...
What is the type of values I have to use to tell the database to store pics?
View 4 Replies View RelatedI 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.
hi can anyone tell how to use the image field and add an image in a database. i'm using visual studio web developer express edition 2008 and i want people who visit my website to be able to see the table and the images associated with some of the rows in the table

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?

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.

I just wish anyone could give me any ideal, like, white pages, or manual on how do I insert BLOB data (Images) to MSSQL 2000 database using VB 6. I need to know exspecially the VB Code and the SQL Portion if you have a store procedure code for that it will be nice.
:confused:
The URL address is for example http://backup/pics/19980.jpg
On the report when I right click on an image the URL is http://localhost/reportserver
I do not understand what is going on. Please help.
Many thanks,
