featured image in database but not in backend - wordpress

to my understanding, the information about the featured image of a post in WordPress is being stored in the database in wp_postmeta table with key _thumbnail_id ...
I have the weird situation that for some posts where there is a features image set in the database, this image also shows up in the WordPress backend in the featured image admin widget -- but for other posts there is a featured image set in the database, but it doesn't appear in the WordPress backend.
see screenshots (sorry, in German) of the database entry plus WordPress backend for both situations - upper where the issue appears, lower where the image also shows up in the backend
What I want to achieve is having all featured images also showing up in the backend.
(we're talking about hundreds of posts, so it's not really an option to manually edit each of these postings).

I found what causes the issue - in case someone else runs into this problem, too:
Years ago I was using the NextGen Gallery plugin which obviously was sustituting WordPress' core system for featured images (don't know whether the actual version of NGG still acts like this, though). Meaning: It stored the attachment_id of the features image at the right place, but did put only the smalles thumbnail version of an image into the regular folder for images in WordPress and kept the bigger versions of the image within the NGG system. Hence: There is a feautres image, but WordPress can's access it ...
Eventually I had to go throug more than 100 posts to fix this manually.

Woocommerce Product Images Blurry Tried Everything

I hope this community can help. I see there is a lot of information on Woocommerce blurry product images and I've tried the fixes to no avail. We recently migrated our site and although all the products in our shop are fine, each time we try to upload and create a new product, the main product image is blurry.
Here's two examples. (1) Good product listing
And (2) here's the test with problems
Using Onetone wordpress theme and have the current installs of Wordpress and Woocommerce. Changing the thumbnail size and regenerating did not solve the problem. Neither did changing the image size from 100% declaration to 'auto' in Woocommerce.
The problem seems to be wordpress is using a much smaller thumbnail (we did not change any sizes after migration) and this is causing the blur because the images are being blown up. Here's the code I found for the image:
The image 'source' for this in particular is:
src="http://liquescencemedia.com/wordpress/wp-content/uploads/2016/08/Liquescence-Time-Travel-Mens-Ash-Grey-1-275x275.jpg
And as you can see, somehow this size is being used for the product image although we've uploaded a much larger size (1000x1000).
On the image details attachment page everything is fine, the resolution is high.
So I'm quite frustrated with this. Why is it calling a 275x275 from uploads when I've uploaded an image 1000x1000? How can I change this?
Any help is appreciated. Do know that I've already been through the Woocommerce literature and it doesn't address this problem.

blog cover image thats not in the blog post

I've been asked to integrate a blog into an existing website.
The blog content will be hosted with an external blog provider (im thinking wordpress and blogger) and I would then import the posts onto the clients site via an ATOM feed as this is the simplest way I can see of doing all this.
The issue I'm facing is that when the blog list is displayed on the clients site they want to use a grid based layout with a cover image. Another stipulation of the design is that the cover image should also not be part of the actual blog post content.
Ideally it would be great if the blogging provider (wordpress/blogger) supported uploading additional metadata and images that do not go into the blog post's HTML content.
I cant find any way of doing this currently and am wondering if I have any options other than rolling my own mini blogging platform for the client or installing wordpress locally and setting that up.
Any ideas?
WordPress will let you upload a custom header image. See: http://codex.wordpress.org/Custom_Headers - this will be useful if you want the same header image on every page. If you want a different header image 'per post' then you'll need a plugin to do that. There are some good plugins that do that in the WP plugin repo: http://wordpress.org/plugins/

Creating wallpaper website site in wordpress

I'm trying to create a wallpapers site, using WordPress platform. The website should have similar functions like this wallpapers site. Which plugin is required to re-size images in multiple sizes, like 1920x1200, or 1920x1080. If there's no such plugin, how can I create this function in WordPress?
You have two options for this:
Manual: Uploaded images can be edited and cropped to the required size by teh administrator. Go to the media library, find the image, click edit and make the changes necessary
Automatic: I found this page by typing "how to edit image size in wordpress" when I was, in fact, looking for a manual that would explain with screenshots the instructions in step 1 above: http://www.wpbeginner.com/wp-tutorials/how-to-create-additional-image-sizes-in-wordpress/
The post there makes use of the add_image_size function of Wordpress and tells Wordpress to automatically generate thumbnails in your required size.
Creating a Wallpaper website in WordPress is now as easy as counting 1-2-3. All you need a WordPress + decent hosting and a Wallpaper WordPress theme from https://binarynote.com
Just install Wallpaper WordPress theme along with their bulk image uploader plugin and you are ready to upload your wallpapers. The theme is able to generate different image sizes like you have mentioned automatically but will not store any such images on your server.
here is one such theme for your ready reference. https://binarynote.com/wordpress-theme-wallpaper.html
Hope this will help you a lot.

Resize uploaded images in wordpress

I have this news portal i built, and the client want a different size of the featured image.
I all ready made my first desired size and they have posted around 200+ posts all ready with that image size. Now, if i change the size it only changes on the new posts / or re upload of the current featured images(which is too much to do by hand).
My Question is, is there a way to resize the uploaded images?
I've never used it, but I think the Regenerate Thumbnails plugin does that.

Re-process all Images in WordPress

I've got a blog that has the highest-resolution version of all its images embedded in the posts, rather than a thumbnail linking off to an image attachment page.
Can you tell me how I can re-process all embedded images so they're output as reduced size thumbnails that link off to their own attachment page (which is WordPress default settings)?
Am I right in thinking I can involve the Regenerate Thumbnails plugin in this?
That was just about what I would suggest, it works wonders, but it will take longer depending on the amount of photos.
Another thing you can do is run the images through an optimizer before posting to speed up load times.
I don't know about this plugin but there is a plugin called auto post thunbnail for wordpress. I have used it and it works great. You just press the generate button and wait till it generates thumbnails for all of your posts, if they have an image in them.
