We can choose Height or Width (or both), but it’s hard to manage vertical /horizontal images if we don’t want them to turn square… A third choice Greater size would be welcome

Glad you like the plugin. So you want a profile that somehow figures out the aspect ratio of the image and adjusts itself accordingly? Sorry, probably not going to happen as the underlying (TXP core) function needs to store the physical dimensions and the plugin can’t rewrite profiles on the fly.

As an alternative, have you considered this bit of trickery:

1. create two thumbnail profiles, one called Wide and one called Tall
2. set the Wide profile’s height and leave its width 0 so it auto-scales the width in proportion
3. set the Tall profile’s width and leave its height 0 so it auto-scales the height in proportion
4. when you want to display the thumbnail, employ some smd_if magic to determine which to display

For example:

<txp:images category="some_cat">
   <txp:smd_if field='<txp:image_info type="w" />' operator="gt" value='<txp:image_info type="h" />'>
      <txp:smd_thumbnail type="Wide" />
   <txp:else />
      <txp:smd_thumbnail type="Tall" />
   </txp:smd_if>
</txp:images>

How’s that for a workaround? You’ll waste a bit of disk space storing two thumbs for each image when you really only want one, but you can decide if that’s an acceptable trade-off.

to avoid the use of the image_info

Out of curiosity, why avoid it? Does it not do what you want? If you take the category attribute out of the <txp:images> tag in the code I posted then I think it does exactly the same as your code (because <txp:images> automatically reads the article image if you use no attributes), and it’s shorter.

Mmm. First real effort at using this fantastic plugin and getting an error message:

Tag error:  <txp:smd_thumbnail type="large" /> ->  Textpattern Notice: Unknown image.  on line 1038

Profile name is “large”, the profile is active and there is another profile which is default. Even without the type attribute no thumbnails display and the error message persists. Mmm!

Edit: 4.3 install.

Somewhat tangential to my post above, on the entry for <txp:images /> on TextBook – the attribute auto_detect="" is a little unclear.

If you wish to turn off the automatic check, set this to auto_detect=”“….

Then later, it says something which appears to contradict that:

<txp:images auto_detect=”“ /> displays all images in the database.

I am using smd_thumbnail to display thumbnails entered in an article image field. Normally, this field might contain several images id’s, but in case there is nothing entered in the field so nothing should be displayed.

Using the following code (with nothing at all in the article image field), what I see is all images inside the database – did I miss an attribute setting?

<txp:images break="">
    	<li><a class="thumb" name="<txp:image_info type="name" />" href="<txp:image_url />" title="<txp:image_info type="name" />"><img src="<txp:image_url thumbnail="1" />" alt="<txp:image_info type="alt" />" /></a>
			<div class="caption">
				<div class="image-desc"><txp:image_info type="caption" /></div>
			</div>
		</li>
    </txp:images>

Tags should definitely be opt-in – that’s good behaviour IMO.

Looks like <txp:smd_if_thumbnail /> needs to be used in a form – I get an error using this on a page:

<txp:article limit="100">
<txp:if_individual_article>
	<txp:output_form form="portfolio_gallery" />
<txp:else />
	<div class="portfolio">
		<txp:permlink class="portfolio_item">
			<txp:smd_if_thumbnail>
				<txp:images break=""><txp:smd_thumbnail type="large" /></txp:images>
			</txp:smd_if_thumbnail>
		</txp:permlink>
		<txp:excerpt />
	</div>
</txp:if_individual_article>
</txp:article>   

Error message:

Tag error:  <txp:smd_if_thumbnail> ->  Textpattern Notice: Image tags cannot be used outside an image context  on line 2312

Am I right?
