I'm not sure about the built in functionality for it, but you may want to take a look at this;

Required b2evolution Version;
1.8, requires the updated auto-p plugin, get it here;
http://evocms.cvs.sourceforge....hrev=v-1-8

I updated the file _auto_p.plugin.php, but don´t fix my problem.

In version 0.9, when i update a photo, this is the text to add to the message:
"<a href="http://www.ramiro.inogest.com/blog/blogs/media/casa 299.jpg" target="_blank"><img src="http://www.ramiro.inogest.com/blog/blogs/media/casa 299_thumb.jpg" alt="" /><br />Clique para ver a imagem no tamanho original<br /></a>"
and it create a thumb to see in blog, and if we want see the photo in original size, we click in "Clique para ver a imagem no tamanho original".

In version 1.8.6, when i update a photo, this is the text to add to the message:
"<div class="image_block"><img src="http://www.ramiro.inogest.com/blog/blogs/media/blogs/Amitaf/f035.jpg" alt="" title="" width="1024" height="768" /></div>"
and don´t create the thumb.

If you want, you can see what i says in my blog.
The last 3 photos are updated with version 1.8.6.

Someone help me?

Sorry, got held up with other things.

The gallery plugin, will create thumbnails for images uploaded with the gallery plugin (in the add/edit post page, their is a gallery button).

As for b2evo's own capabilities for creating thumnails i would have no clue.

AFAIK b2evolution has never created thumbnails automagically. Way back before plugins happened there were quite a few different methods to hack it in. I tried some of them but was not successful, though many people obviously were.

Currently I believe balupton's gallery plugin is the best way to get that feature, but I have no personal experience with his plugin. After I gave away my digital cameras I don't do a lot of image work is why.

thanks for both.

Now i understand, and i install the plugin, and it works well.
