WordPress does do some compression on images when it resizes them. You can disable this very simply using the following code (or using a plugin like this one): function wpse_114909_image_quality() { return 100; } add_filter( ‘jpeg_quality’, ‘wpse_114909_image_quality’ ); I’m sure that GD & Imagemagick are not as good at resampling images as Photoshop is, so … Read more

I don’t know if TimThumb is really necessary. You could easily do that with internal WordPress functions. Add this code to your functions.php: <?php add_theme_support( ‘post-thumbnails’ ); // this enable thumbnails add_image_size( ‘preview-thumb’, 300, 185, true ); //this sets your default size ?> Use the following code instead of your code above. <div class=”main”> <div … Read more
I think, you can not exactly determine, but you can assume one with header data. $headers = wp_get_http_headers( $url ); $mime_type = $headers[‘content-type’]; $ext=””; foreach ( wp_get_mime_types() as $exts => $mime ) { if ( $mime == $mime_type ) { $ext = $exts; break; } } Now in the $ext variable, it could be multiple … Read more
Use : $img = wp_get_attachment_image_src( get_post_thumbnail_id(get_the_ID()), ‘full’ ); $img_src = $img[0]; refer this : http://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src
The tip in Part 2 at the site you link that reads Unzip the database you’ve downloaded and open it with text editor (Notepad++ or Dreamweaver) and use “Find and Replace” option to change “http://olddomain.com” with “http://newdomain.com” and then import it with phpmyadmin. is absolutely wrong. Running a find/replace on a database dump with a … Read more
