Controlling dpi and size in Picasa

I need to submit some jpg images by email. The specifications are greater than 300 dpi and, when printed, have the long side no bigger than 6".

I use Picasa and have no idea how to accomplish this. If I crank down the dimensions to 640 (which would limit the output size), the dpi goes down to 150.

If I act as if I'm going to print at 4x6 and if the image began as the full sized one, it's 370 dpi. The problem is that I have not found a way to save the image in this configuration. The only way I found to save is at the print preview page and it required to save as bmp and it's the image of the whole page, including the white page.

Any suggestions?

Or if you don't know about Picasa, do you know of another (inexpensive/free) program that will do this?

hi bonnie, i don't know how to control the dpi in picasa.
An alternate program which is free is "gimp". it's available for both windows and mac and it has a lot of features, probably will do what you need. there is a learning curve, tho...

Re: Controlling dpi and size in Picasa

There is a very handy and simple program that I use a lot, not usually for editing pictures but for viewing them. It is called Irfanview. It is totally free and you can change an image size and resolution in it. Once you open an image in Irfanview, you can go to the menu - Tools>Resize/Resample image - and set a new size in pixels, centimeters or inches, as well as change the DPI. It may not be Photoshop, but it is free, quick and easy.
