search image on a web site

[fxs]

Hi,
Thanks for your great products and support.
Please have a look at this web site: http://info-radiologie.ch/

search the french word "genou"
I didn't find the location/place/way to correct the size of the thumbnail/image in the results page.....
Any hints?

What are supposed to do the readers to get the images of the brain, abdomen, (or whatever) etc. I mean: if i write image and abdomen, i can get multiple pages...and no image! What is your idea, your advice to achieve this goal in the medical part of this web site?
thanks
best regards

You can specify the size/appearance of your thumbnail images via CSS. This is explained here:
Q. How do I set thumbnail image size or alignment via CSS?

I am not exactly sure what you mean by your second question, but the answer to most questions regarding setting up thumbnails and images can be found in the image support pages here:
http://www.wrensoft.com/zoom/support...ins_image.html
http://www.wrensoft.com/zoom/support...ge_layout.html

You can either associate certain pages with images (e.g. the page about "abdomen" could have a ZOOMIMAGE meta tag which points to an abdomen image). Or you could make sure that your image files actually contain meaningful meta data, so that there are keywords associated with them. This is explained here:

Hi Raymond,

Thanks very much for your support.
The first question is solved. I missed that.

...
<a href="pangkor_beach.jpg"><img src="th_pangkor_beach.jpg" alt="Screen shot of Pangkor beach"></a></p>
...
</html>
This is the result produced by the above HTML source code:

I didn’t find the solution of the second question.
If you search:”shoulder mri image”, you have the correct page: shoulder-mri.php but not sign about the image of the shoulder. If you look at the source of the page you’ll see a lot of lines including code like that
alt="Shoulder MRI - Image 11 of 13".
Nothing is specific/related to this page. Same thing for brain, etc.
file extension is ok. Indexing option is ok (alt).
Any thoughts?
Thanks and best regards

I had a look at your page, and the first thing I should point out is that it is not quite what it appears to be due to your use of Javascripts which dynamically load and hide/display the fullsize images. That is, although your page shows the fullsize image with the ALT text when you hover the mouse over it, in the HTML, it is actually the thumbnail which has the ALT text, and the fullsize image is only an anchor link. I thought I should point this out first should people refer to this in the future and get confused.

So in your particular example, the page is here:
http://www.info-radiologie.ch/shoulder-mri.php

And the HTML in question is this:

<a href="irm_epaule/fullsize/irm_epaule_1_fs.jpg">
<img src="irm_epaule/thumbs/irm_epaule_1_tmb.gif" alt="Shoulder MRI - Image 1 of 13" title="" width="99" height="100" />
</a>

The problem is that the ALT text is only being indexed for the file in the image link, which in your case is the thumbnail. Presumably, you are not indexing the thumbnails (probably by skipping the "/thumbs/" directory), otherwise, your search for "shoulder mri image" would likely returned the thumbnail image. The ALT text however, is currently not being indexed for the fullsize image.

This is a bug in that it differs from our documented scenario, which is that the ALT text should also be associated with the linked image. We will look into this and should have a fix for it for our next build (V5.1.1008, hopefully out sometime this week).

and

the thumbnail which has the ALT text

I agree with you but PVII Galleries degrade gracefully in older browsers and are fully accessible to user agents that are not JavaScript-enabled.

The zoom software did not skip the various thumbnail directories.
If you use the exact phrase “irm cerveau” you got thumbnails and fullsize image.
If you use the exact phrase ”brain mri” you got nothing. Whereas there is
the code: alt="Atlas of Brain MRI Anatomy: Axial T2-weighted images - Figure 3"
Sometimes for the French language you got only the first thumbnail or also nothing.

Perhaps it happens when an image is linked to multiple web pages (whatever the language)?
Other cause?

Yes, it does this well - it still shows them, but only the thumbnails (until you click on them to load the full sized image separately). I'm just pointing out that the HTML is very different to how it appears rendered on the page (i.e. the fullsized images are in fact never displayed on the page in the HTML code, but the Javascript makes them appear with the ALT text available).

If there are multiple links to the same file throughout your website, Zoom will only use the ALT text from the first img link it came across, when crawling your website. It will not get the ALT text from links found elsewhere on your site (since the file may have already been indexed at that point). So, it is possible that the ALT text will not be indexed if it was not specified in your first link to the same image file. The solution to this is to make sure you have the same ALT text for the image file whenever you link to it.
