Can remember if i posted anywhere else but in case i didn't here is my guide to creating manageable pictures for web.
Put simple, how big a picture is is determined by the number of squares / cells / pixels. Cameras normally report this in millions of pixels (i.e. 10 mega pixels), while websites and software normally user the number of pixels for width and height. When producing pictures for the web it is usually more than good enough to use a 640 x 480 (i.e. 640 pixel wide by 480 pixel high).
When you take a photo using digital camera, especially with new cameras, they have huge numbers of pixels to allow them to be blown up. Before posting these it is simple to create a copy of the image in a more manage size, i.e. 640 x 480 pixels. This can be done in any piece of software where photo editor, photoshop, irfanview etc and is usually called resizing or resampling. If you do not have a piece of software all the free ones are pretty much the same, I tend to use Irfanview as it is simple but it is personal taste.
Here I will describe how to re-size an image in Irfanview. The method will be simliar in any software you just need to find the menu option.
- Simple open the picture you want to resize.
Then under Image in the menu across the top, select Resize / Resample.
The menu that appears will show you the current size of the image in number of pixels. If your image is lanscpae (wider than it it tall) then you can simply click in the box next to 640 x 480. If your image is portrait (taller than it is heigh) then find the box that shows the current number of pixels for your picture and type 640 into the hieght box. You will see the width is automatically set to the correct size.
Click on OK and you image will be resized
Save the file, make sure you use Save AS to create a new file as you do not want to over-write the original
I hope that helps. I am creating a PDF document with pictures of all the menus etc for my inlaws so I am happy for the site to put that somewhere if it helps.
