This question may be related to a resolved thread.

I’m using the code below and the image outputs just fine, but this error is thrown at the top of the page.

I’m simply trying to output an image similar to the way I have below and dynamically pull the image width and height. If there’s another way to do this, please let me know!

Code:
{portfolio-image}
{path}_small/{filename}.{extension}
{/portfolio-image}

Hello Adam,

Welcome to the forums and to the community! It’s good to have you here.

I am sorry to hear you are running into this problem.

This sounds like this bug as far as I can tell. Your situation is a bit different but the error is exactly the same. Can you give the fix listed a try and let me know if that works?

I will be on the lookout for your reply.

Cheers,

Thanks Shane, that seems to have worked.

My next question, is how do I pull the dimensions of one of my custom thumbnail groups? The _small makes it pull the correct image, but it’s pulling the original dimentions. I’ve tried many variations that I’ve seen here and there. portfolio-image:small, width_small etc. nothing worked.

{if portfolio-image}
 {portfolio-image}
  {path}_small/{filename}.{extension}
 {/portfolio-image}
{/if}

Hello Adam,

I do not believe that the height and width are available for the thumbs.

What do you see when you view the source. Does the width and height remain tags or is some value placed there? Would think the values for the portfolio image would be used.

Cheers,

Same problem here. It is returning the width of the original image (925) instead of the small image size which should be 300

Width:925 | Height:512 | Small Width: 925

<ul>
{exp:channel:entries channel="test_channel" limit="60" dynamic_start="on" disable="member_data|pagination" }

 {post_image}Width:{width} | Height:{height}{/post_image}
 {post_image:small} | Small Width: {width}{/post_image}

{/exp:channel:entries}
</ul>

Anyone found a solution yet?

Hey Media Kitchen,

I think what you are looking for is the Thumbnail Variables.

Each file upload directory may be set to automatically generate thumbnail versions of an uploaded image file. You may display the following information for each auto-generated thumbnail:

height
width
size
file_url

The variable for each of the above is created by combining the resize setting short name with the desired information, separated by an underscore. For example, if you have two resized images created with shortnames ‘small’ and ‘medium’, the code to display the url for each would be:

{small_file_url}
{medium_file_url}

Cheers,

Thanks for the reply Shane

So are you saying to get the width of an image with a short name of “small”, I need to do the following?

<ul>
{exp:channel:entries channel="test_channel" limit="60" dynamic_start="on" disable="member_data|pagination" }

  {post_image:small} | Small Width: {small_width}{/post_image}

{/exp:channel:entries}
</ul>

Hello Mediakitchen,

Did you test that block of code? It looks close.

Are you generating thumbnails?

Cheers,
