How to display an image from data base into a HTML Field [message #1844335]

Hello
I need to display an image inside a html filed, How can I do that when I fetch the image from database and it does not exist under icons folder, the HTML.getimageByBinaryResource( CharSequence s ) does not provide a solution for this and I think the name is incorrect here We dont pass a binary resource but a charsequence.
Is there any solution with the Eclipse scout SDK 11.
Kind Regards

You might be able to call the addAttachment(...)/(setAttachments(...) method on the HTML field with the binary resources which actually contain the images and afterwards you can use them with <img src="binaryresource:file_name_of_binary_resource.jpg, see https://eclipsescout.github.io/5.2/latest/scout_migration/scout_migration/scout_migration_guide.html#html-field - this migration guide however describes a much older version of Scout, I am not sure if everything is still the same with the current version.

For information, I used the code in an other thread and it is not working
is was recommended to use AbstractImageTile instead

The goal is the create image insode tiles when switch to tile mode in table

@Override
protected ITile execCreateTile(ITableRow row) {

BinaryResource img = BEANS.get(IMyService.class).getMYImage(id);

AbstractImageFieldTile imageFieldTile = new AbstractImageFieldTile() {

@Override
protected String getConfiguredLabel() {
return "Label";
}

@Override
protected int getConfiguredGridH() {
return 2;
}

@Override
protected void execLoadData() {
getTileWidget().setLabelVisible(false);
if (img != null)
getTileWidget().setImage(img);
else
try (InputStream in = ResourceBase.class.getResourceAsStream("images/not_found.png")) {
getTileWidget().setImage(new BinaryResource("not_found.png", IOUtility.readBytes(in)));
} catch (IOException e) {
throw new ProcessingException("resource", e);
}
getTileWidget().setAutoFit(true);
GridData gdh = getTileWidget().getGridDataHints();
gdh.horizontalAlignment = -1;
getTileWidget().setGridDataHints(gdh);
}

};

return imageFieldTile;

}

This is not working in case of table
