I use Access 2007
I have created an OLE field to store JPEG, so I can easily drag them into DATABASE.
That works. Trouble is: This field does not dispaly the JPEG but the generic JPEG thumb and I need to double click to open the JPEG and preview it.
Is there a way to preview JPEG without having to double click on it ?

Have you considered storing your images entries for your database as 'text', and simply store the path for the image(//pics/mypic.jpg), rather than the image object itself? If your database is on a shared drive, you can create a folder in the same folder as your database to hold your images. When inserting an image, you can have a textbox and simply type the relative path to that image. This will prevent your database from inflating in size. From there, it is just some simple code to display the picture.
After setting your database up to just store the path names of the images, you can follow these easy instructions on how to display these images on forms : Microsoft Knowledge Base
I recently switched a couple of my databases from using OLE's to text fields with the path name of the picture and am really satisfied with it.
You will need to use an Attachment data type to display anything other than bmps. Only bmp images will display in an OLE field (see the Northwind sample database for an example, the Employee form shows bmp images stored in an OLE field).
Alternatively, you can store the path to the image and show it in your form with some VBA. In general, it is best to store paths to images, rather than images, even with databases that have much higher size limits.

How can I insert an image data in MySQL Database and then retrieve it using Golang?
Basically I want that task for upload profile picture of user in web application.
According to the my knowledge,the best solution is save image as blob object in database.Is it best solution for upload image in webapplication in golang.?
Please help me find the best solution for that.I want to find the solution in golang.I am beginner for golang programming.
converting image to a blob and save it in the database is a somewhat long process and it may cause issues sometimes. The easiest way is saving the image to a server (or a local directory) and saving the image path in the database. In that way we can access the image by using the image path in the database. This, will show how to save image path and access it and converting image to a blob and save it in the database.

I have a base64 encoded image stored in my database as a blob, and I want to insert it into a Crystal Report without a fileupload field. I looked all around the internet and can only find ways with a file upload field.
I read somewhere that you need to load a binary code in sql if you want to display an image.
So I have a binary code in MSSQL/MySQL server with varbinary(max) that I load into the crystal report, but the image is still not showing. I do see that it's an image though because I see the red X.
Should I still convert the binary value that I have from sql server to something? Is what I'm trying to do even possible? If so, please describe the way to do it.
I am a complete novice, doing some work on a HTML5 drag and drop game. I am looking at coding tutorials which will save an image of the game when the user presses a button. The canvas image is saved as a DataURL. I kind of understand what this means. But my questions are: where does the image save to (as you don't seem to need to specify a location) & will an image saved to that location always have a unique URL (i.e. images saved from different games wont overwrite).
The Data Url is just a Base64 encoded string which represents an image. I'm not sure about your exact implementation, but you almost always would have to save that string at some persistent location. Try the Local Storage for instance if you want to save the image on the user's machine and not on a server.
Otherwise, you can always POST the Base64 encoded string via Ajax to your own server and save it in a file or database.
I have an Access database that I am working on, and need to extract the images from a few CommandButtons on a Form and save the images as files.
I haven't been able to do this using VBA. Anyone done this before or know how to do this?
I've used some of the Access built-in images, by using a simple graphics program to capture the screen image, then saving it to whatever format you require (eg bmp etc).
An OLE Object column contains images but the image type (jpg/gif/tiff) is unknown. These images need to be extracted from the DB and saved to disk using VBscirpt.
I've done this before in Delphi, the solution was to use the clipboard (somehow the clipboard can determine the type of image). Copy the contents of the field to the clipboard and then save the contents of the clipboard to a file.
OLE objects is bad way of storing images in MS Access. Use OLEToDisk to save your images as pic files.
After that reimport them in nice way. Check AccessImagine for working with images in Access - it does all the hard job.
Here I found an example to take a screenshot with VBScript and paste it to MS Paint. Maybe you can modify it to do what you want?
