Wordpress regenerates thumbnails on each load - wordpress

When I'm working in localhost, every uploaded image in wordpress generates thumbnails and after that I can edit manually these thumbnails and replace .jpg files with the edited ones. But when I placed my site online, every time I load the home page, it generates all the thumbnails AGAIN and that erases my edited thumbnails. I also assume that makes my site slower.
Is there a way to disable that?

How to have thumbnails in different folders than the original image show up in media library?

We are migrating a database from a custom CMS to WordPress and one of the challenges we are facing is that the previous CMS stored thumbnails in different folders than the original image (folders also include second and if the thumbnail was generated a few seconds later it would be stored differently) and we are mapping those for the WordPress thumbnails (as there are hundreds of thousands and we do not wish to regenerate what already exists).
The issue is that WordPress automatically wants to add the folder structure of the original image to the thumbnails and therefore breaks the URL.
Consider original is:
2018/12/13/06/18/22771810000000_43_240.jpg
We are storing the full path of thumbnail images like below (serialized in postmeta):
2018/12/13/06/19/22771810000000_43_240.jpg
WordPress displays thumbnail like so:
2018/12/13/06/18/2018/12/13/06/19/22771810000000_43_240.jpg
How can we tell WordPress not to add the trailing folder schema from the original image?

How to make quick edits to images uploaded to media library

When I have images uploaded to Wordpress, there is no way for me to flexibly edit these images. For example, let's say I want to add a colored overlay over an image that has been uploaded to Wordpress. For me to do this, I have to add the overlay to the image, then upload the new modified image to Wordpress. When I am developing a non-Wordpress site, however, all I have to do is link to the photo in the CSS, then using the Image Assets generator, the linked image is changed on the fly. This saves me from having to re-upload photos every time I make a change.
Is there any Photoshop script or plugin, or just a method in general for editing photos without having to re-upload them to Wordpress?
There isn't any script out there that I know of, but if you have access to the wordpress uploads directory via an ftp client, you can edit the originally uploaded file and then use a plugin like Regenerate Thumbnails to update the smaller and automatically generated images.

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.

Wordpress Plugin: Thethe Image slider - image links

I have moved my wordpress site onto a new domain -
everything else is working fine, except for my sliders made with "The The image slider". It imported the sliders, along with their slides. however - the image paths of the images still point to the "old" site, and therefore the image slides are not showing?
I have tried to adjust the permissions of the cache folder in CPanel, and all the permissions seem in order. I have also done a "search and replace" with a plugin and according to the plugin result, all the paths are changed? I can open the slides images by using the new path which shows that the images are in the new upload folder, however the path to the images is still the "old" path in the plugin's slider settings
Is there someway I could perhaps change the image paths to the new domain?
