I have a developed a wordpress website by installing a pre-developed theme from themeforest.net. When i try to upload an image, the image successfully uploads but the preview/ thumbnail isn't generated only for file sizes over 1 MB. The max file size i can upload is 8MB. Please Help!
I tried uploading increasing memory and execution caps. Nothing worked.
You're not giving a lot of information, so I'm suggesting a work around.
Reduce the size of your images with cropping them to the needed size. Compress JPG and PNG images.
Online Image Compression
I checked my website in Google page speed insights and the score is only 38/100.
I can see that heavy images are the main cause of this problem and most of the server load is being used by the images. How can fix that issue?
Tried PNG format of jpg images. But when I convert jpg to png image size increases.
use like http://gtmetrix.com/ and Analyze your site’s speed, they will provide the optimized version images, you have to rename and upload it on the same path. or you could compress using any site like,
Jpg image:
https://compressjpeg.com/
Png image:
https://compresspng.com/
In my WordPress setup I use the TinyPNG plugin to compress uploaded images, which works very well when I used it with WordPress image sizes (add_image_size()). I now develop themes with Timber and use the resize function of TimberImage as it is much more convenient and does not generate every version for every image, which is never needed. The only problem is that resized image versions of the original compressed images are always bigger in file size than the original, especially for PNG files, because the resize function cannot save it with the same "compressed" algorithm. Does anyone have a solution to this problem other than moving back to add_image_size()?
Metadata is information about an image, and can be included in JPEG image files.
EXIF metadata is information about the image recorded directly from the camera – for example, the exposure time and the date the photo was taken.
WordPress preserves EXIF information in full size images loaded to your website. It will also extract the Exif data to make it available for plugin developers.
When WordPress uploads images, in addition to uploading the Full Size image it automatically creates several differently sized versions of the image. By default: a Large, Medium and Thumbnail version.
The problem is that Wordpress is stripping the EXIF data when resizing images. The resized images become "orphan".
An "orphan" work is a work to which copyright cannot be determined or a work where the determined copyright holder cannot be contacted.
In the era of responsive images, it cannot be that the solution to keep the EXIF data of an image is to use the image in full-size.
Question:
How to force Wordpress to keep EXIF data?
Digging further:
Is there a way to insert the EXIF data in resized images once they have been resized?
Is there a way to force wordpress to use another Image Processing System that is not stripping metadata from images?
How to force Wordpress to keep EXIF data?
Switch the image processing to imagick. Your server must have it installed though.
Either by using the plugin that does that,
https://wordpress.org/plugins/mhm-forceimagemagick/
or by adding the code in your theme:
add_filter( 'wp_image_editors', array( $this, 'allowedEditors' ) );
public function allowedEditors()
{
return array('WP_Image_Editor_Imagick');
}
Is there a way to insert the EXIF data in resized images once they have been resized?
You would have to create your own functional that extend the class-wp-image-editor-imagick and include them in your functions file.

Answered above.
I want to genrate a thumbnails of image without save its differentlty
ImageResizer supports resizing images and it can output the thumbnail to a stream (for example a MemoryStream), so you don't have to save the image on disk. It has a very good support for ASP.NET and it can be installed using NuGet.
