The original image size (i.e. ‘full’) is never modified. Intermediate image sizes are controlled in various places: Default image sizes ( ‘thumbnail’, ‘medium’, ‘large’ ): core settings, via Dashboard -> Settings -> Media Custom image sizes: Theme functions.php file, via add_image_size() Post Thumbnail size ( ‘thumbnail’ ): Theme functions.php file, viaset_post_thumbnail_size()` By default, the ‘large’ … Read more
I found and modified a chunk of code found here: http://www.wprecipes.com/wordpress-tip-detect-if-a-post-has-at-least-one-image. <?php while ( have_posts() ) : the_post(); $content = $post->post_content; $searchimages=”~<img [^>]* />~”; preg_match_all( $searchimages, $content, $pics ); $iNumberOfPics = count($pics[0]); if ( $iNumberOfPics > 0 ) { //your loop content goes here } endwhile; ?> I think this just looks for images entered … Read more
I’d say it’s a Database Issue. If it were the actual image it wouldn’t show up. I’ve had the same issue before but with only a few images luckily. I believe it was caused by a database error. I was having issues on the shared server at the time, and imported quite a bit of … Read more
The simplest way to do this is to change your field to return attachment ID instead of URL, and then when you need the URL, use wp_get_attachment_image_src with the ID. The only method I’m aware of to get ID from URL is with a custom SQL query.
<?php $imageid = get_post_meta($post->ID, ‘imageembed’, true); if($imageid != ”) { ?> <div class=”newsimage”><img src=”https://wordpress.stackexchange.com/questions/57967/<?php echo wp_get_attachment_url( $imageid ); ?>” width=”640″ /></div> <?php } ?> Use if condition to check if $imageid has any value in it or not.
Why not use Links Categories? There you can use images, descriptions, create categories and sort out everything. There would be no need to create a widget as you can use the default WordPress one. Case you were to create your own widget, you can query these items with WordPress functions.
If you’re adding the full size image from the Post Editor, when you select the image from the media manager pop-up box, you’ll click the button that says “None” under the Link URL field. That would be impossibly messy to control programatically. Well, maybe not impossible, but probably something that you would just hack with … Read more
The “medium” and “large” are not custom image sizes – they are already part of the core WordPress media sizes and they should be handled via the “settings” -> “media” options page in wp-admin. Give your custom image sizes a different and more unique name (reserved are thumbnail, medium, large, full)
