Ok, when you have an image that you want to put on your site but you need to adjust the pixels and size, is there a way to do it? Do you need special software? If so, anything free or not expensive to help you do this.
Replace '60' with the size you want it and im sure you can guess the rest but that's the general code.
Or you can download free software called GIMP its an awesome tool at editing images and completely free, it may come in useful for other things too instead of just resizing images.
I'd definitely download the software and resize the image that way. The image editing software, like the one Rob mentioned, will do a much better job.
If you need to shrink an image, do not adjust the size in the browser. The visitor will still download the larger image, but the browser will resize it so it will still take more time to download.
I will have to agree too, force changing the image size in img tag can reduce the image quality when shown in browser, it is better to create different size images using a graphic program and let the img tag show the actual size in image. It is a little extra to work, but you get a better quality display.
