I am having difficulties when trying to insert files into a SQL Server database. I'll try to break this down as best as I can:
What data type should I be using to store image files (jpeg/png/gif/etc)? Right now my table is using the image data type, but I am curious if varbinary would be a better option.
How would I go about inserting the image into the database? Does Microsoft SQL Server Management Studio have any built in functions that allow insertions of files into tables? If so, how is that done? Also, how could this be done through the use of an HTML form with PHP handling the input data and placing it into the table?
How would I fetch the image from the table and display it on the page? I understand how to SELECT the cell's contents, but how would I go about translating that into a picture. Would I have to have a header(Content type: image/jpeg)?
I have no problem doing any of these things with MySQL, but the SQL Server environment is still new to me, and I am working on a project for my job that requires the use of stored procedures to grab various data.
Any and all help is appreciated.

Insert one image into SQL Server This table will have an integer (int) id and the image column named img. The data type that we are going to use to store images is the varbinary(max). The INSERT statement inserts the value 1 as the id and then inserts the image named 1. png from the folder img in the c drive.
Retrieving and Display ImageClear the image of the picture box if there is image. Create Connection to the Database. Create a SQL command object call cmd by passing name of the stored procedure and database connection. Set CommandType Property of the object cmd to stored procedure type.
The IMAGE data type in SQL Server has been used to store the image files. Recently, Microsoft began suggesting using VARBINARY(MAX) instead of IMAGE for storing a large amount of data in a single column since IMAGE will be retired in a future version of MS SQL Server.
One of the most frequently asked questions is how to store and retrieve images from a database. Because images cannot be inserted into the database by using the SQL INSERT command, the only way to insert images into database is through embedded SQL programming.
The image type is deprecated, so don't use that.
The short answer is to use the FILESTREAM type if this is SQL 2008, or varbinary(max) if it's 2005 or earlier.
The better answer is to use the FILESTREAM type if this is SQL 2008, and not store images in the database at all otherwise. Databases aren't built for this type of thing and throwing BLOBs in there can hurt performance significantly. FILESTREAM sidesteps the issue by storing the actual data on the file system; everything else is a sub-standard solution.
As for how to read and write to a varbinary column if you choose to take this non-ideal approach, it's going to be represented as a stream in PHP. That's what you get out of a query as the column value, and I believe that's what you have to put in as a parameter.
