GTMetrix, image attributes & Nivo Slider

Hi Hariprasad. I use Photoshop to edit and optimise my images. Its the actually dimensions that I need to specify in the css I think so that the GTmetrix scan does not throw up a notification on it and a low score.

Hi,

I think Charlie is right. Function show_nivo_slider() in wp-nivo-slider/wp-nivo-slider.php is used to display image.
you can specify image size here. You can see a code like
<?php query_posts( 'cat='.$category.'&posts_per_page=$n_slices' ); if( have_posts() ) : while( have_posts() ) : the_post(); ?> <?php if ( '' != get_the_post_thumbnail() ) : ?> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"> <?php the_post_thumbnail(); ?> </a> <?php endif ?> <?php endwhile; endif;?> in that php file.
<?php the_post_thumbnail(); ?> is used to display image. You specify image size in that function. Check the following link for description.
http://codex.wordpress.org/Function_Reference/the_post_thumbnail
Remember one thing, you are using responsive theme, sometimes the slider image may not fit to the screen if you run the site in low resolution device. Anyway try it.. Ask if you have any doubt.
Good luck..

I dont understand how to add the attribute 940 x 355 to this code can you show me?

Hariprasad Vijayan comments:

Hi,

You can specify image size like <?php the_post_thumbnail(array(940,355)); ?>

Steve Watson comments:

sorry guys this is like a foreign language to me. I have not idea where to put this code you are sending me. the nivo-slider.php file is quite big with load of code. When i do edit>find I cannot find where this particular bit of code is.

Hariprasad Vijayan comments:

please show me the code..

Hariprasad Vijayan comments:

i mean nivo-slider.php

Hariprasad Vijayan comments:

you can see these code in show_nivo_slider() function in wp-nivo-slider.php

Try following code in your theme js.

jQuery(document).ready(function($) { $(".nivoSlider img").attr("width","940"); $(".nivoSlider img").attr("height","355"); });
