Image will not display on page

Frank

Question

Hello everybody,

I add an image by saving its binary data and filename into a table. When I query this database table for that image to display on the page, the image will not display.....even when I hard code the table's ID into the query for that record. I get an "X" where my image should show. What is the deal? It is a straight forward query.

On the Image widget, I set the followling attributes:
Image - Blank
Type - Database
Filename - " "
Attribute - SummaryInfo.Images(This is the field where the image is stored.)
Entity Identifier - IntegerToEntityReInteger(11)

Hi Frank,

Be careful when using hardcodes (your Entity Identifier property value)... are you sure that the entity record id 11 does exist in the database?

Please check the post at https://www.outsystems.com/forums/discussion/7174/image-widget-type-database/ ?
There's a sample .oml there that might be just what you need.

Also, let me suggest Service Studio Online Help on Using Database Images which applies to this situation.

Happy coding!

Hello Frank,

To resume, Keep It Simple..If you need to get an image dinamically from your database, use a query in you preparation to perform it ;)

Kind Regards,

Hi Frank,

Think you need to give a filename to your image.
Without that the response mimetype gets a default value and most browsers won't render the image without a mime type matching the image format.

If that doesn't work, are you sure the binary is correct in the database?

Ahhhhhh........here is the issue with image upload that maybe Outsystems should try to address.

The ImageUpload widget allows you to load any kind of file formats....ie word docs, notepad docs, etc. Outsystems should limit this ImageUpload widget to upload file formats to .jpg, .png, etc.

The reason is that the Image widget can only display .jpg, .png, etc files and not word docs, notepad docs, etc. files.

I was uploading a screen shot that I took and dumped on a word doc and I was able to upload that doc using the ImageUpload widget, but the Image widget does not display word documents.
