no veo la imagen destacado cuando pincho en las categorias

[julio_jag_cc]

Hola amigos!! tengo pequeño problema que no me deja dormir, os explico.

Yo en mi pagina principal de wordpress tengo habilitadas las imágenes destacadas y cada articulo lo voy clasificando por diferentes categorias...
El problema viene cuando yo quiero ver los articulos de una categoria en especial, que las imagenes no se ven los unico que me sale es leer mas.
¿sabriais como deveria hacer para ver tambien las imagenes en las categorias?? ¿algun codigo? o ¿algun plugin?

MAs vale una imagen que mil palabras xDD



Gracias por todo...

[Nicoeas]

Código PHP:

<img src="<?php echo catch_that_image() ?>" alt="<?php the_title(); ?>" width="95" align="left" style="margin:0 5px 5px 0;"/>
                    <?php the_content_limit(350, "Leer M&aacutes...");?>
 

fijate si te sirve....

[julio_jag_cc]

Creo que podria valer, pero tengo una duda, donde lo deveria copiar en el functions.php del tema o en el category de wordpress??

Gracias por contestar.. Salu2.

[Nicoeas]

en el category.php.... sino no va a andar....

[julio_jag_cc]

Gracias ahora mismo pruebo y te digo...

Salu2.

[julio_jag_cc]

Nada, al agregar ese codigo, no me carga ni si quiera la pagina....

alguna otra solucion??

Salu2 y gracias.

[Nekko]

Es que copiar y pegar a lo bonzo códigos no sirve de nada, ese trozo de código necesita de enunciar la función catch_that_image() para que funcione.

Yo ya escribí sobre esa función varias veces, aunque les diré que empieza a quedar obsoleta, hay alternativas mucho mas elegantes, como el plugin wp smart image de Metacortex.

FIN xD

Que theme es? De donde lo puedo descargar?

[julio_jag_cc]

Te mande un MP con la direccion para no hacer SPAM...

Salu2.

[Nekko]

El theme por defecto no trae para hacer eso que querés (algo que yo no había interpretado).

Abrí tu archive.php y buscá:

Código:

<div class="post" id="post-<?php the_ID(); ?>">

Luego de esa línea colocá:

Código:

<a href="<?php the_permalink() ?>">	<?php postim(); ?> </a>

Las imágenes deberán estar marcadas como "imagen destacada" en cada post para que las muestre.
