Display a specific image from assets

Question

I'm trying to grab a specific image to display that is located in assets. I tried using {% set image = craft.assets.filename('image_filename.jpg') %} but I get the error "An unknown image object was used." I also tried referring to one of the asset sources which I saw as a solution in another post related to my question: {% set image = craft.assets.source('my_images') %} but I'm not sure how that would help me grab a specific image. {% set image = craft.assets.images[0] %} just grabs an image from any of the asset sources if I change the index number. What am I doing wrong here?? Thanks in advance!

Answer 1

You can do

 {% image = craft.assets.id(x).first() %}

Where x is the ID of your element. You can see the ids of your elements in your cp. There is a little wheel icon below your asset sources where you can define which attributes to display. Just check the selectbox for id

You can learn more about fetching entries with ElementCriteriaModels in the docs

Your problem was: you did not fetch the element. You prepared your database query but you need to execute it with first() or find() because
