I was sent images from a 7 mp camera over email, but they are not the original size. how do i change that?

Question

I was sent some pictures over email that were taken by a 7 mp camera (yes it was set to best quality 7mp). When I downloaded the pictures they were only the quality of about a 3 mp camera. I can't enlarge them from the size they currently are without much pixelation. Is there some downloadedable software i can use to bring them back t their original size, or do i need to have them sent again? Does yahoo have a size limit or something?

Good morning;  

     Jimmy's response is one I agree with.  There is also the point that usually the picture file size you get from your camera is not the same as the camera sensor size.  A 7 Mp camera might produce a 3 Mp JPEG or ".jpg" image file due to the compression built into the JPEG conversion process.  You can make the file smaller for transmission over the Internet.  In any case, as Jimmy said, if the detail is not there, no program is going to generate it for you.  There are some things you can do in PhotoShop, such as "sharpening," but you still need to have something to work with.  This is one reason why the professionals usually use a RAW file format for their pictures; they save everything.  

     Some Internet Service Providers (ISP) and e-mail hosts do have a limit to the size of a file they can accept.  They do seem to be getting larger, though, in general.  Check with yours and ask what file size limits they may have.  You can adjust your images to work with that limit and get the best picture you can from that limit.  The only disadvantage to the larger file size is the longer transmission time.

If you need to send huge files, use http://www.yousendit.com  Free account lets you send up to 100 MB. (It doesn't actually send a file to anyone. It sends a link - and when clicked, the file is downloaded from their server).

A paid account lets you send up to 2 G (for one file).

If you use Picasa2 for your photo storage, you can export original sizes to another folder, then e-mail the image from that folder.

This is what happens when images are sent via email, they get downsized. There are a few very expensive programs that purport to upsize images, but even they can't add detail and sharpness that isn't there. Basically, you have to get the images one at a time at the full size, there is no way to upsize the images and recover al he detail they had. All email service have size limits, usually limiting each email to no more than 10MB each. That would mean you could only get 1, maybe 2, images at that resolution per email.
