I created the script to resize thousands images in a single-run Python command in Linux (Ubuntu). This will also work in Windows i guess. It can resize thousands of images ( I run it before for > 50K images)
Suppose we have images stored in Folder structures like this :
images
---- Tigers
Description: Resize the image to a new width and height. To make the image scale proportionally, use 0 as the value for the wide or high parameter. For instance, to make the width of an image 150 pixels, and change the height using the same proportion, use resize(150, 0). Once we upload the image to the S3 bucket, we can get the function to resize the image to the size we need on the fly. In this article, we walked you through setting up a dynamic image resizing API with Python and the Serverless framework. Image resizing is a great use case for Serverless.

........
ans so on.
Run the script with this steps : Bitmap image software free download.
1. Open your terminal, and type
2. python resizer.py {img source folder} {the size you want the image to be} {destination folder}
example :
python resizer.py /home/ubuntu/images/ 128 /home/ubuntu/new_images
3. Drink your coffee and watch the terminal running the process
Notes:
1. Install PIL image if you dont have one ( another library considered faster than this)
2. ANTIALIAS and quality=90 is to prevent the image from downgrading quality for Down-Scalling
3. This code works for Down-Scalling resize , yo can use another method beside ANTIALIAS for Free-Scalling
4. Images will be converted to .jpg extension ( its up to you, you can change it your way)
5. If you have different folder structures from above example, modify the code

Here we’ll be doing many operations on an image using OpenCV functions. To make this session interactive image of Thanos(A character from a famous movie ) is being taken for example.
Various operations of OpenCV in Python
The various operation goes as follows:
Importing the required libraries required for the program
cv2 is the OpenCV library and the numpy library is included as many times the image will be treated as an array.
Reading and displaying of an image – OpenCV Python
cv2.imread() is a function which takes image name as a parameter(provided the image is saved in the same folder where the program is or else just give the path to the image) and cv2.imshow() display the image with name and its parameters are (‘name_of_the_window’,variable_in_which_image _is_stored). The output is given as:
Printing the dimensions of an image in OpenCV
Normally, the dimensions are width*height but OpenCV takes as height*width. The output will be as: (175, 289, 3) as displayed for my image. The values are (height, width, channel) where the channel is the RGB components.
Resizing of an image in Python with OpenCV
As seen in code the height and width are specified as 300. Both values are then inserted into the variable called dim(dimension of new image). The third line uses the function cv2.resize() which actually does the main work of changing the size. The parameters are the original image, dimension, and the algorithm to be used for this purpose. For time being we are not going to focus on the algorithm but sticking to the implementation part. The output after this is:
Rotation of an image in OpenCV
As we know now image.shape() returns a tuple up to indexing 2 where the first two values are height and width hence the first line extracts the values of height and width, We then discover the center coordinates by moving towards half of both height and width. The function cv2.RotationMatrix2D returns a matrix that contains the image of rotated coordinates. The parameters are center, angle_of_rotation(here we are rotating for an angle of 180 degrees) and scaling factor. Later the transformation is done by cv2.warpAffine() function whose parameters are the original_image, obtained matrix and the dimension of the rotated image. The output is:
Cropping of an image in Python
The first line returns that part of the image which starts and ends between (beginX:endX), (beginY,endY). This crop the image. Just for fun, we crop to get the Thanos’s gauntlet. Picsart software download for pc windows 7. The output is:

The basics of OpenCV ends here.
