How to resize image

How do you resize the pixel size of pictures and not damage the quality of the pictures?

I am trying to get some images smaller to go on a webpage in dreamweaver but everytime i try to reduce the size the picture is totally messed up.

How can I correct this?

Thanks in advance!

 

You need to create a smaller version of the image using a paint program that can do resizing using a scalar technique like 'bicubic' or 'bilinear' - sometimes called 'smart size' when both are applied. Most of your better paint programs like Photoshop, Paint Shop Pro or the GIMP have this.

What you do NOT want is a 'bicubic' resize - this is what most (not all) browser engines do - they just throw away excess pixels instead of blending them into the image. The net result is less than attractive.

Your problem could also be that you are dealing with palettized images (stored as 256 color or less) which do not allow for that type of filtering. You have to promote them to 16.7 million colors in your paint program of choice, then resize.

Resizing in dreamweaver is like using dreamweaver to do much of anything else - a waste of time.

 

download gimp http://gimp-win.sourceforge.net/stable.html

open the image in gimp, click on the resize tool, make sure the "chain" is linked. then enter pixel size in either field.

 

u can use adobe fotoshop...or acdsee is best,,,because its tools are very best

 

If you have a lot of pictures to resize, my recommendation is Eyebatch.
You can automate your image processing by applying image commands to a set of multiple images.

 

almost forgot, haven't tried it yet but adobe photoshop has a free online version now https://www.photoshop.com/express/landing.html

If you want to learn to resize images without using a graphics program-- see this article.

Q...

 

I find the Image Magick suite to be quite advanced. See the convert -resizing utility for the simplest, and likely the highest quality method. Or, see thumbnails for more thorough info.

Running a command line utility is amazingly more productive than using a GUI for this type of operation. For example, go to your images directory and enter

  mkdir thumbs
  mogrify  -format gif -path thumbs -thumbnail 100x100 *.jpg

Code (markup):

That will grab each .gif file in the directory, create a thumbnail that will fit 100×100px box, and store the .jpg thumbnail in the thumbs directory.

Comparisons of graphic programs' down-sampling found here.

Since you have Dreamweaver, I assume you have a picture editing program to go with it?

In Fireworks or Photoshop, select the picture, click on the Scale Tool and resize your picture, then right-click on the image and click "Crop Document", this will resize the layer to the size of your image, instead of leaving white space around it when you save it.
