How to Change Picture Size?

I have a desktop computer that has Windows XP. When I upload pictures to this computrer they stay small in format size (ie. 25 kb per picture or 50 kb per picture or 125 kb, etc.) so this makes it easier to burn alot of pictures to CD. I also have a laptop with Windows Vista, when I upload pictures to this computer they are very large (ie. 1.5 mb or 2.0 mg per picture). How do I keep the pictures small when I upload them from a memory card to Windows Vista? I would prefer NOT to download anything but want a solution as to why pictures are so large on Vista and not on XP.How to Change Picture Size?
The size of a picture file is based on the amount of information it is holding and the type of file not your operating system. A setting on your camera has changed.How to Change Picture Size?
Bmp (bitmap) format takes a lot more space then the JPG format. If those bigger pictures are in bmp format, i will explain you an easy trick to convert them to JPG format, which will make them smaller.



Right click on any large sized picture, and open with -%26gt; paint (you can also open ';paint'; and browse the file)

Once you opened a picture with paint;

File-%26gt;Save as-%26gt; -here switch the save as type to JPEG. -%26gt;save.

You won't see the difference between JPEG or BMP, but size reduces significantly



By the way, this is not caused by your Operating System, all photo's have different quality, which changes their size gradually.
