I have images stored in the database that I want to show in Spotfire. I've found how to display an image from a webpage but not one directly from the SQL database. Spotfire defaults to string type for the image. I tried editting it at the Info Link stage and forcing it to be a blob, but when I render it as an image I just see [..].
unfortunately Spotfire doesn't support BLOB or binary data.
what you can do is store your images on a server somewhere, then in place of the binary data in your database, store the URL to the image. you can then display it in a table as suggested in the Spotfire manual.

I am new to both BLOBs and image rendering in Shiny, but I am wondering if it is possible to render images stored as BLOBs in an Oracle table via datatables in Shiny? Unfortunately I don't have code to share, but am wondering if anyone has attempted or been successful doing something like this?
Basically, I am wanting to have a table stored in Oracle that has a product picture, and then several more columns with other information about the product. Then, I would like to be able to read that table in via R and display the full table with the images as a datatable in a Shiny application.
I would like to know how one can display image type BLOBs uploaded as per this stack overflow question Use of BLOB type column in Oracle APEX, as images in a classic or interactive report instead of the normal download links.
I noticed that you can change the blob column attribute's Content Disposition field to inline, which then allows you to click through to another page where the image is displayed; but I want the image to display directly in the report without having to click on it.
The inline image displayed in a new page has the following url
https://apex.oracle.com/pls/apex/apex_util.get_blob?s=34564408462&a=4794&c=16789110088070077&p=2&k1=21&k2=&ck=D4QFl4Z9txsufDbmUOmKeirK4&rt=CR
which suggests that one might be able to use apex_util.get_blob. Does anyone know how this can be accomplished?
I have implemented same in classic report.
I followed this link http://docs.oracle.com/cd/E14373_01/apirefs.32/e13369/apex_util.htm#AEAPI129

Actually I am new in SSRS(SQL Server Reporting Service). I have to display signature image in SSRS Image Control.The signature image is stored in nvarchar datatype.If you required in other information then ask me.
Thanks in advance.

SSRS Image Control displays string image data fine, with no extra settings.
Just Drag an Image control in the Report and in Image Properties General tab,
choose Select the image source: as Database
and select the appropriate field in the Use this field: option. i.e the db field which holds the image data.
and select proper MIME in Use this MIME type:. Though any of them should work for you.
I Have developed a reporting tool using ms access. It is composed of 10 forms which allows the user to input data. I also allow the user to upload images to the database(images are uploaded to image folder and the link is store in the database table). The user could upload as many as 30 image files.
What i want to do is add another form which displays all the images the user has uploaded. Would this be possible in access i know in php you can use the mysql_num_rows function , just wondering is their a similar way to achieve this in access. Can anyone point me in the right direction ?
Basically when a form opens i want to run an Sql statement that retrieves all the images in the tables database and then shows the images on the form.
Using MS Access 2010:
\1. Create a continuous form, there is a wizard that will step you through. You can base the from on a table or query, a query is usually best. Ensure you include the field that holds the path to your image. You do not need to include the field with the path to the image on the form, it just needs to be part of the recordset.
\2. Add an image control
\3. Set the control source for the image control to the name of the field that holds the path to the image.
\4. View the form.
The continuous form can be a subform
I have a table view in my app and would like have a left-side-image for every cell. This image should come from an sqlite database. What code would I need to use for this?
you should review fmdb. check the main.m file for an example of storing and reading an image file.
