I am trying to use my webcam to take a picture and save it into an Access database with other information like first name, surname etc.
I have so far created a page that is able to insert the other details into the database. I now don't know how to go about with the image.
For now, I need help on how to capture the image and save into Access table.
One way you could handle this would be to instead of inserting the image, you could store it in a relevant folder with the database'images', then instead insert the path to the image.
However if you need to have it in the db, you could use attachments to table records. Ive never done this, but from a glance it looks limited. As MS access databases max out at 2GB.

I would like to put photos in my phpmyadmin database but I can't find the solution that allows me to do so. I made an image array with a varchar but I can't find the path that allows to put an image. I thank you in advance for helping a young beginner ❤️
The best solution is to store the image as a file on disk and put the path to the file in the database (as a varchar or some other text type), then your application references the file instead of loading the BLOB data directly from the database. There are performance reasons that are well documented elsewhere that explain the intricate details better than I can, but basically the database slows and the amount of disk space it takes up expands as you store the images in the database.
If you decide to defy that advice and store the image directly in the database, you shouldn't be using phpMyAdmin as your main interface. Don't get me wrong, it's fully capable of uploading the image, but presumably you'll have some custom application interface that you should be using instead that also does application-level logic. But that's not what you asked, so to do this in phpMyAdmin, there should be a "Browse" button near the field on the phpMyAdmin Insert page. This requires your column be some appropriate sort of binary such as BLOB.
I did some research and the web has taken me all over the place and I still haven't found a suitable solution or guide to what I am trying to achieve.
I read up a similar post to what I am asking. Except that's #php
Retrieving Image in SQL Server (varbinary)
Update:
The "conventional" way is the create file directory and file path. This was my initial method to get the front end up and running for the user.
My sup actually advised that I use this hash method nonsense which he can't even explain properly to me.
A user must be able to insert an image on the form, generate a report displaying the image as well.
How does the varbinary work to link sql and Access for what I am trying to achieve? I am currently playing around with my development to resolve it.
Any clarification?
I have no other way of putting this question after my first edit.
This is the form
For each form entry a user should insert a picture to support the Findings.
A VARBINARY field in SQL server is a field that stores binary data, and is often used for storing files. You can fit entire files in this field.
If you have a VARBINARY field in SQL server, and create a linked table in Access to the table with that field, it gets interpreted as an OLE object, since OLE objects are binary data too.
You can use the Bound object frame control in Access to save images into OLE objects, both as an image (which is displayable), or as a package. This does not require any code. You can right click the field -> Insert Object -> Bitmap Image to insert bitmap images into an OLE field. However, this stores OLE object data along with the image data, which makes it very hard to work with using code, and nearly impossible in non-vba applications. Using this approach is only justifiable if you're sure you're going to stick with Access for the lifetime of the database, in my opinion.
I've shared an example on working with VBA code and the OLE object here, but that uses hacky code that executes GUI operations. It's nearly impossible to port to other applications. I recommend you use the next way instead.
Alternatively, you can directly store binary data in the OLE object/Varbinary field. This makes it a lot easier to deal with using VBA code or any future application, since it's just the file data stored in the field, there's no OLE object data stored with it. I've shared code to load binary data in a field and save it back to disk here.
The hard part of this puzzle, if you're just working with binary image data, is displaying the image to the user. I've shared 3 approaches here, with code for one one of them. However, that's quite complex VBA code.
I do know that there is a answer here
But I want to know these:
I know how to save them programmatically, but I don't know what data type to save them? Could I still use image datatype when I have converted my images as image to 256KB? Or should I save them into filestream data type?
What kind of fragmentation is the document about? In my scenario, I have 2k+ employees and counting, so that means my application would get bigger over time, If I saved the images as image, and did not followed the rules as stated by the research paper, would my images lose their intact picture? (e.g a picture with blue background somehow changes its color maybe?)
Should I save it in the exact table of my employee details table? Or should I save it in a different table?
Sorry but I did not really understand the NTFS thing, is it the RAM of my computer? Or the RAM of my server? And I am using a file server as my database, should I still convert my images or should I go with using image data type without the conversion?
If you want to save files of any type in SQL Server then you should use the varbinary data type. You would use varbinary(max) unless you know that the files will be small. You can then convert your images to a Byte array and save that to the database.
You can enable the FILESTREAM option on your SQL Server instance these days and it will then store the data outside the main MDF file although that will be transparent to your code, so you keep using the same queries as you would otherwise.
I'm working on a SQL server database and I need to have pictures
its for a catalog and most pictures are 1-4 mbs I don't thing embedding the pictures in SQL will be a good idea
what the best solution
till now I used to use access
I would really like to make a wpf form
but when I make a data source I don't understand exactly how linked images work
my main point is that I need it to run really quick and print out a catalog with inventory info each day for thousands of items
I'm looking for a form to manage it
I have tried an access form but access doesn't handle good the linked pictures
Just store the path to the image in the database.
Or, if using SQL 2008 or higher, there is also a new table called FileTable that stores data in the file system directly.

"I need it to run really quick" If speed is a must, Access might not be a good choice for this.. You should use a more professional RDBMS, IMHO.
If this is a hobby project I'd suggest using sqlserver express (I assume you have microsoft knowledge) and either storing a link to an image on the file system/web server or storing the object in the db. For small data volumes either way is likely to perform fairly well.
It is all very easy in MS Access 2010, just bind an image control to a table of paths. For example, my table is called Pictures, with the following entries.
PicturePath
Z:\Users\Fionnuala\Pictures\abc.png
Z:\Users\Fionnuala\Pictures\abc.jpg
I now just need an image control on a report bound to the table Pictures with a control source set to PicturePath, the images will be displayed.
I have an MS sql server database. There is a table with one of the column of the "image" type. Now, the customer wants to read the data from an MS access. He wants to display the images in a form.
I have never used access and have no idea of how to do simple things there. Any help will be greatly appreciate.
Thanks,

Rather than write out the stored images to files in order to display them, it may be possible to use ASP to display the image and a web browser control on the Access form to display the page. I have not tried this.
How To Display Images Stored in a BLOB Field: http://support.microsoft.com/kb/173308
You can put regular Image control on form and state MyPic.PictureData=PicField in Current event.
Or you can use AccessImagine, which is great for pictures in MS Access and requires no scripting. You can download it here - http://access.bukrek.net/download
I think you can do this by using streams. Stream the image from the field to an unbound image control. We use the same process for opening documents and other binary data stored in an SQL Server database.
On the other hand, Access had an Image control that can be linked to a field in a table. That should be a lot easier to user!
