Marco Zinn	Monday 16 November 2009 12:21:21 pm Hi there... I'm trying to create a download (!) link to an image file. To be precise, i want a download link to an image ALIAS file. What I have is a link to the original file using this template code line: <h2><a href="/content/download/{$node.data_map.image.contentobject_id}/{$node.data_map.image.id}">download</a> </h2> I think, that URL code is not documented anywhere, but i just found it by tweaking file download URLs. What i need is a download link to e.g. the "thumbnail" alias of the image attribute of the current node. By "download link" i mean, that ez should sent HTTP header for DOWNLOADING the image, just like a file download. Currently, i only have a link, which SHOWS the image: <a href={$node.data_map.image.content[thumbnail].full_path\|ezroot}> Well, let's hope, that this post actually gets posted...

Hi there...

I'm trying to create a download (!) link to an image file. To be precise, i want a download link to an image ALIAS file.

What I have is a link to the original file using this template code line:

<h2><a href="/content/download/{$node.data_map.image.contentobject_id}/{$node.data_map.image.id}">download</a> </h2>

I think, that URL code is not documented anywhere, but i just found it by tweaking file download URLs.

What i need is a download link to e.g. the "thumbnail" alias of the image attribute of the current node.

By "download link" i mean, that ez should sent HTTP header for DOWNLOADING the image, just like a file download. Currently, i only have a link, which SHOWS the image:

<a href={$node.data_map.image.content[thumbnail].full_path|ezroot}>

Well, let's hope, that this post actually gets posted...
