new to digital- how to make the photo smaller when emailing?

by mkaresh / May 24, 2006 6:20 AM PDT

I recently bought my first digital camera (Canon A610) and have been using Picasa to edit (am loving both of those). Right now when I attach a photo to an email it is *gigantic* (I think you know what I'm talking about- you scroll to the bottom of the email to see a nose, scroll over to see their eyeball), how do I go about making it smaller on the email? I'm exporting the photos from Picasa to My Pictures and attaching to an email from there.

Thank you!

I don't find an easy way to reduce the size of a photo with Picasa.

If you send the email directly from Picasa, it will reduce the photo size automatically.


If you would rather do the reduction yourself you can download the free Irfanview program and use it.

With Irfanview, you open a photo and then at the top of the screen click "Image" and then click "Resize/Resample". That will present you with a page that gives you many choices for reduction size.

This tiny program works like a dream, just hilight the pics you want to reduce in your pics folder and right click. Lets you choose from a variety of sizes and it can do a whole batch at once as well.

You can get it there, it's 100% FREE!!!

Hi ! Joe, Photo size reduction....

Photo size can be reduced by the physical size, i.e. the dimensions, or by the resolution (i.e. number of pixels.). What difference is there when that photo is enlarged to its origional size at the receiving end ? Obviously, if the pixels has been reduced, we cannot add them back, whereas, if only the dimensions has been changed, the same number of pixels remain ?

This gets confusing.

You normally see the resolution set to 72, if you turn off resample and change to resolution to 300....
the file size remains the same.

The only thing that is affected is the ''printed'' size of the photo.
It will look the same on the computer screen.

At 300 you will get a small print.
but it will look really good.
At 25 you will get a large print.
but it will look poor.


If you reduce the dimensions of a photo file, you toss away some pixels and reduce the file size.

You can then take that reduced photo file and do a ''resize/resample'' and make it back to its original size.
Pixels are added by interpolation.
The result is a same size file as the original but the quality of the image is degraded.

Joe, if the original image is 22 inches wide I do a save-as down to 10".

Pixles just confuse me. Why not work with inches at 70 dpi?
After all, it is still low res at 70 dpi.
Maybe an image saved-as down to 7" wide x 5" high would be better to send over the internet at 70 DPI? Still shows up nicely to a screen image.
5"x4" would fit also. Just a thought here.

Heavens! Pixels are what a digital image is composed of.

If you throw them away, you are losing part of the image. Without resampling, changing an image's size merely changes the number of pixels displayed in an inch or centimeter or whatever unit of measure you use. I hope you're not taking an image which is 1,540 pixels wide (22 x 70ppi) and saving it with a width of 700 pixels (10 x 70ppi). If you are, you are throwing away more than half of your image data. What usually happens is that you keep the 1,540 pixels, but display them in 10 inches (154ppi) rather than 22 (70ppi).

However, if you are really sure that you never want to see anything more than 70ppi with a width of 7 inches, then you should resample the image. The result will be a width of 490 pixels.

BTW, I know dpi is bandied about the internet as synonymous with ppi. It really isn't. Most usage of dpi applies to inkjets these days, and it means dots per inch. That's not the same thing as pixels per inch. My printer's lowest setting is 720dpi, and its highest is 2880dpi. That does NOT mean I need images with 2880 ppi.

Picasa and Outlook Express
by eric1514 / May 29, 2006 1:40 PM PDT

If you start your email session in Picasa, the program will resize any and all photos you select.

What I mean is, start Picasa. Select the photo you want to email. It will show up in the "tray" at the lower left. Click the hold button to keep it there. Do this with every photo you want to send.

When you are finished, click the email button and you will be given the opportunity to select your email program. All photos will be attached and resized when you send the mail.
