The only directory in which you have guaranteed write access is the uploads directory. Even your plugin’s directory might be write protected, the same for wp-content (which doesn’t even have to exist).
You should not attempt to know the user device on server side, as this kind of thing will mean you will not be able to use any page caching, and it will fail when the browser “window” size changes. Do such decisions on client side. If it is impossible to simply use CSS, just prepare … Read more
You can easily use Regenerate Thumbnails and bulk regenerate for all the images. Regenerate Thumbnail plugin updates all the details about the full size image, as well as it recreates thumbnail. It’ll update the dimension for each image, but all the other image sizes should be registered as well, else they won’t be stored in … Read more
Note: you shouldn’t remove any of the default images since they’re all highly used throughout the WordPress admin. For example, on the media library page all those image blocks are technically “medium” sized images scaled down. If you click an image it will display the “large” image if possible. Otherwise, these default to show a … Read more
Not a direct answer to your question, but possibly a resolution to your problem. Downloading the same image from another source likely resulted in an exact copy (hash-wise) since they probably got it from the same source you did. A wild stab in the dark here, but it’s possible there’s something about the image data … Read more
Your css is doing it. Replace following css if not being used anywhere else. If you’re not comfortable then ask your designer to do it line 1213 .thumb-box { position: relative; width: 100%; height: auto; } line 2321 .box img { -webkit-transition: all 0.3s ease; -moz-transition: all 0.3s ease; -o-transition: all 0.3s ease; -ms-transition: all … Read more

Try to see if this works, I used scandir because I prefer it. The problem was that glob, like scandir, only works with paths on the server’s file system, not URLs: function footer_image(){ $imagesDir = get_stylesheet_directory() . ‘/images/footer’; $imagesUri = get_stylesheet_directory_uri() . ‘/images/footer/’; $images = array_diff( scandir( $imagesDir, 1 ), array( ‘.’, ‘..’ ) ); … Read more
Learn to use the developer tools in your browser; see Firefox or Chrome or Safari or IE to look at the rendered browser source to locate the URL for the image. The image could be loading from a third party, the theme folder, etc. Using dev tools is more reliable than simply viewing browser source, … Read more
