I know for Google Shopping (or whatever it's called now) it's recommended providing the URL to the highest quality image there is for the product. Does that same principal apply for Product rich snippets?
Although it's rendered on the product page, I can easily provide the URL to the high-res image like this:
<meta itemprop="image" content="/img/high-res.jpg"></meta>
Or I can just tag itemprop="image" to one of the lower quality images that is shown on the website? But it's only 400 x 400px, compared to high-res which is 2000 x 2000px.
Any thoughts?
For some Rich Snippets (including the Product Rich Snippet), Google does not recommend any image dimensions, for others, they specify
at least 160x90 pixels and at most 1920x1080 pixels
(taken from my answer on Webmasters SE)
If you want to provide an image URL without showing the image, you must use link instead of meta:
<link itemprop="image" href="/img/high-res.jpg" />
(Side note: The meta element has no closing tag </meta>.)
I am creating a website for the first time with Bootstrap3 and have a page with 3 images which will be links to galleries. These images are not thumbnails.
I have alternative images (B+W) for hovering and so my code currently changes the image from colour to B+W on hover.
I want to be able to also include a text overlay on hover so people will know to click through to the gallery. So, I'm looking to add text on hover to the B+W image. Alternatively, I would make the colour image less opaque and add text to that, if it's easier!
Here's my html code currently.
<img src="landscape.jpg" alt="Landscape" onMouseOver="this.src='landscapebw.jpg'" onmouseout="this.src='landscape.jpg'" class="img-circle img-responsive">
Thanks in advance.
try adding a title attribute :
<img src="landscape.jpg" alt="Landscape" onMouseOver="this.src='landscapebw.jpg'" onmouseout="this.src='landscape.jpg'" class="img-circle img-responsive">
I currently use retina.js to load Retina-optimised images on my website.
It is great, but renders redundant all thumbnail links to larger images (which load with Fancybox).
My question is how can I disable all links to images if Retina is detected? (At least until I have a higher-res camera.)
Regards
Paul
If you want just some images on your page to be excluded from retina.js, you have to add the data-no-retina attribute to the tag, like this:
<img src="yourImage.jpg" data-no-retina />
If you want to disable the links created by Fancybox, you have to modify the Fancybox source itself.
I'm working on a gallery type application - one template puts together a popup dialog for a larger view of thumbnail images when clicked. The server path to the image is included as a template variable.
Gallery.Templates.Popup = "\
<div class='popup'>\
<img class='popup-image' src='{{image-path}}' />\
<div class='name'>{{name}}</div>\
<div class='caption'>{{caption}}</div>\
<div class='dimensions'>{{dimensions}}</div>\
<div class='price'>{{price}}</div>\
</div> \
";
This works very well EXCEPT for the first time the image is loaded. The dialog is constructed and shown but at the time the html string is attached to the dom, it lacks the image. The problem it is causing is in positioning the dialog:
The dialog box is positioned in the middle of the screen like this:
left = window.width /2 - dialog.width/2
But since the image is not present, the dialog.width variable is incorrect. Again, this only happens the first time a thumbnail is clicked, I'm guessing the image is cached for subsequent clicks.
Would this be handled by prefetching the images somehow? If so, do they need to be attached to the dom in order to be cached or can I just load them in an array?
Many Thanks !
If you can get the image size ahead of time from the server, you could use that to help you size the '.popup' div appropriately.
It sounds like a bad idea to prefetch images if they aren't needed and I can't think of a way to ensure that a specific image is loaded before it's html is generated programmatically.
Rather than add Pin It buttons through our site, I would like to simply control what images show up in Pinterest's "Find Image" results if a user decides to pin one of our URLs.
As of now, "Find Images" allows the user to scroll through the images it finds on the page so they can select which image to pin. The "found" images start with the first jpg in the html file, I'm assuming (could that be a bad assumption??). On our site, this forces a user to scroll through about 15 navigation and promotion images before arriving at the featured product image. Is there any way to specify this image to show first in those results? Maybe through a meta tag, or by adding a class or id to the element?
Without a public Pinterest API, this seems like just guesswork, but I wanted to see if anyone else has run into this, or solved this. Thanks.
A lot of search results including the Pinterest Help Center talk about using nopin in HTML elements, which is invalid HTML. What they don't document is a data attribute to the same (well formed) effect.
<img src="foobar" data-pin-nopin="true" />
Adding the nopin attribute will exclude the image from appearing on Pinterest:
<img src="..." nopin>
I solved this by simply loading the image before all others in the page. In this case, I gave it width="0" and height="0" (you could also give it style="position: absolute; left: -9999px; top: 0;" just to be sure).
This won't break the page layout, but will force Pinterest to find this image first. The only downside is that the browser will load the page a few milliseconds slower, but if you're reusing this image later in the page anyway, you should make up for lost time then.
Pinterest will find any images from <img> tags (it will ignore CSS background images) that are at least 80px x 80px.
The order the images show up on in the Pinterest list is determined by the order they are specified in the HTML.
As you have discovered, you can alter the CSS of an image to "hide it" without actually hiding it by either moving it off the page with absolute positioning or 0 height and width. Any images that are set to display: none will not be picked up by Pinterest.
You can instruct the share preview to only grab specific images from the page by using the “image_include” configuration option. First, set image_include to your desired class name (id selectors are not allowed, only class selectors), then add that same class name to each of the images on the page that should be grabbed. For image_include, don’t add the ‘.’ selector. Here’s an example:
<script type="text/javascript">
var addthis_config = {
image_include: "at_include"
}
</script>
Once image_include has been defined with a class, add that class to the desired images on the page. In this example, the only images on the page that will be grabbed, will be the images with the at_include class (img1.jpg and img3.jpg).
<img src="http://www.example.com/img1.jpg" class="at_include" />
<img src="http://www.example.com/img2.jpg" />
<img src="http://www.example.com/img3.jpg" class="at_include" />
I was reading this blog which suggests the following:
Use the global no pin flag to prevent pinning on the whole site
Manually add the Pin It widget to those images you want to make pin-able.
Given Pinterest's webmaster tools appear to only have a blacklist, rather than a whitelist option (that you are seeking), this could be a possible solution. Another stated benefit of this is you can also supply suggested pin text through the Pin It widget.
Only downside to this I guess is that it may break the user's own Pin tools. Pinterest does allow you to supply a custom "denied" message, so I guess you can say "please use our site's pin buttons directly".
I've tried this, and it works. It seems like a decent approach, at least until Pinterest sees fit to add some better tools, such as an image whitelist option. The main drawback is needing to add Pin-it buttons on every image you want to enable for your users & your users may be annoyed that they can't pin anything.
Unfortunately, there is no way to mark several images on your page as preferred, but you can mark one image to stay at the top of your images when someone pin it. Specify this meta-tag in <head>:
<meta property="og:image" content="http://YOUR-DOMAIN.com/IMAGE.jpg"/>
I have not found official confirmation for this feature, but it works great with addthis sharing plugin.
Add this script before the actual call to pinterest. And set images that you do not want to show with a class called 'nopin'
<script type="text/javascript">
var addthis_config =
{
image_exclude:'nopin'
}
</script>
<div id="toolbox" class="addthis_toolbox addthis_default_style">
<a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
<a class="addthis_button_tweet"></a>
<a class="addthis_button_tumblr"></a>
<a class="addthis_button_pinterest"></a>
</div>
</div>
If anyone is using AddThis, please check this thread: http://support.addthis.com/customer/portal/questions/1570789
AddThis has some, uh, unique functionality that affects the image picker presented. As in, when there is only one image on the page, it ignores the defined og:image.
If you set that lone image to be excluded, then the image picker won't show any images for selection.
