You need to resize your images to be able to start using them effectively on websites and blogs. For resizing your images and optimizing them, you may use a free website titled 'simpleimageresizer', where you can cut the size of your image in terms of pixels, or in terms of percentage (30-40% reduction could prove sufficient). Generally, your aim should be to ensure that images are reduced to below 1MB of size, or perhaps even less than 500MB. This would reduce the load on the websites or blogs, and help them to achieve top performance while page loading.

To resize images in bulk, you can use a free image optimizing or resizing software like ImageCompressor. This software can be downloaded for free and you can use it to compress an entire folder of images at once. And that too, while maintaining their quality.

For resizing images, softwares used are:
1) Photoshop
2) Pixlr
3) Image Resizer etc,.
or there are many websites from which resized image can be downloaded after uploading the original image.

But, you should keep in mind that resizing an image leads to loss of some color data in the image (reduction or zoom out) or loss of clarity in the image (expansion or zoom in). The color data lost when reduction cannot be identified by human eye (generally) but there will be some loss. So, resizing should be done considering the above cases.

Hope this answer helps.

There are a lot of software, free versions & paid versions, to resize the images. Paint being the easiest one & Photoshop the toughest one. When you are resizing the images, the image quality can never be the same as the original one. The image quality will surely deteriorate (the image pixelate on zooming out), when you reduce the size of the image. And, it will never improve if you increase the size of the image.

The only point to keep in mind while resizing the image is to keep the length & breadth in the same proportion as the original image. Otherwise, the image or the objects therein appear to be deformed. In Photoshop, there is an option called 'constrain proportion'. One needs to check the box for 'constrain proportion' to maintain the length to breadth ratio so as to avoid the deformation of the objects in the images. In paint there is no such need to maintain the length to breadth ratio, as it automatically does that.

Suppose the image size of the image which you want to reduce is 1024 x 768 pixels, and you want to reduce it to 800 pixels on the larger size
1. Then Paint will reduce it to 800 x 600 when you select the pixel option and put 800 in place of 1024. There is no need to put in 600 for the shorter side. Paint automatically does that.
2. In Photoshop, if you check the 'constrain proportion' box, it will automatically select the other side according to the value put in by you.
