I am no camera buff and I use a point and shoot camera most of the time but I have a nice Canon 16MB on my horizon right now.
I have a neighbor that has the same camera but hers is 12MB and she said anything larger than that is hard to send as she sends tons of pictures to her family in Greece.
My question is: Can these pictures be made smaller so they would be easier to send? OR is this a major procedure. Thanks in advance. Camera specs below

Molly -

Do you have Irfanview? It's not a complete photo editor like Gimp, but, among other things, allows you to resize photos to a pre-determined file size very easily. Even allows quick batch processing (including resizing). Be sure to download both the main program and the plug-ins. Note that this is a windows program, but runs just fine on my mac using wine, and should also work just fine on linux using wine.

Hope that helps!

I'm sure it has size settings -- my new Nikon has about the same mp and it has a broad range. I usually shrink and/or crop before sending anyway. It's better to shoot large than to wish you had more detail later.

ETA: And definitely, IrfanView! I even use it in Linux.

Me too. I was always quite happy or content with point and shoot but sometimes when I see all these fantastic pictures shown here in this forum I thought I might want something a little better but not too expensive.
I liked this one that I posted. It has wifi and I don't understand that. Does that mean I can send pictures right from the camera through email?

Yeah, I think that's what that means, but I'm not 100% sure.

Odin, are you saying that those settings are on the camera?

There are the photos you take and there are the photos you share. I don't expect any GC regular to send a picture directly off the camera without tinkering with it a little... If you have more pixels, you have more options to resize/crop/rework the image, so pixels are good as long as they are not obtained by compromising with other desirable features such as sensor sensitivity and noise.

I don't use Irfanview, but for bulk processing I have a script that resizes the pictures to 3000x2000, boosts the saturation a bit, and sharpens then a bit.
#! /bin/bash

dir=${1:-.}

for f in "$dir/"*.JPG;
do
        echo "Exporting $f"
        convert "$f" -modulate 100,120  -geometry 3000 -sharpen 0x1.0 -quality 85 "$dir/$(basename "$f" .JPG).jpg"
done

This produces the default shareable pictures.

I downloaded the Canon elph 340 manual and those are the in camera settings. Output is JPEG & MPEG-4 (no RAW).

Go with the larger camera. You can always reduce the size of the image file with Irfanview or Gimp or any image software.

Thank you, I don't want to go with a larger camera. I just want to be able to make them smaller so they will easier to send.

If you take a small image directly, it may be too small to give a good print. Take the picture at the native camera size, and make a resized copy of those you want to send.

Yes Gimp is just fine for scaling images. If you don't need to send print quality, rescale in Gimp and your good to go. If you have a save for the web plug-in use it as well. If you need print quality scale using Print Size 300+ PPI first.

You can even start there. The JPEG from the camera is normally very high quality (97 on mine) with no or moderate chroma subsampling. The SFW plugin lets you change the JPEG options(*) (chroma subsampling has a lot of effect on size) and this may be enough to reduce the file size. The JPEG from my 12MPix camera are around 5MB, by lowering quality to 85 with maxiup chroma subsampling the file size goes under 2MB.

Btw, the camera has likely a setting for image quality... You can use that to some extent, you'll lose less by lowering the JPEG quality than by using smaller pictures.

(*) You can also use the Advanced Options in the JPEG export but you cannot check interactively the size of the generated file nor the image quality.

Wow, I am going to have to digest all of this.
I just downloaded that save file for the web but I guess it needs to be compiled. There are several files in the folder.

Your Fedora package manager might have 'gimp-plugin-registry' available already. If so I believe 'save for web' is included. Check the Gimp File menu for 'Save for web' (before export) you might have it already.

Gimp's own, Export as JPEG Advanced Options are all you really need. Just remember to add a *.jpeg extension so you get the proper dialog. Use the dialog Help button if need be.
