image size

[barbara_...@adobeforums.com]

When I change image size to a JPEG for emailing eg from 300 to 72 DPI and the length to 800 ppi from a higher one the new setting does not hold and one or both changes reverts back to original

barbara,

Although I'm not sure I'm following what you mean by "the length to 800 ppi from a higher one", it sounds like you are merely changing the pixel density (ppi), not resampling down to reduce the overall "weight" of a file, which is the whole point of resizing for email. That, or you are accidently not saving and sending the smaller file. Do you rename your resized file to distinguish it from the original?

If you've resampled the image down, you've permanently discarded at least some of the data of the original file -- and there is no way that it can be recreated from what remains, regardless what CSI shows with their miraculous racks of beeping and burping computers. <g> Only lossless file compression schemes (such as zip and sitx) will reduce the "weight" of a file, yet allow it to be fully reconsituted without data loss.

use save for web and reduce the image

Well, I found that there is a large (original) size limit beyond which "Save for Web..." won't work.

I've had success doing the following:

Flatten Image.
Resample down to desired size (using pixel dimensions, forget 72 ppi) using Bicubic Sharper
Save as jpeg; set Quality to highest the recipient will accept.

I've not gotten used to using "Save for Web and Devices" for this relatively simple procedure, but that's just me.

True, but for emailing purposes do you WANT any larger size? I hate it when someone emails me a big honking image that I have to scroll around (or download) just to see.

Me too, Ed.

My brother—who DEFINITELY knows better (because I've explained it to him a dozen times, and because he's a pretty sharp cookie)—sends me huge honkin' images in the body of emails all the time. Ikeep telling him to ZIP 'em up, and he keeps not ZIPing them.

For years now.

siiiiiggggghhhhh...

yep, same here! :)

A friend forwards emails to me from one of his friends that always contain a set of images repeated three or more times in the body, and also attached. It's a miracle they even arrive.
It's no use bitching, they are entirely free of clue.

Barbara,

Follow these steps:

1. Image > Duplicate > OK
2. Image > Mode >8 bits
3. Edit > Convert to Profile > srgb
4. Image > Image Size

constrain proportions
resample

change resolution to 72

choose 800 pixels for the longest dimension

bicubic sharper > OK

5. Open image to 100%
6. Filter > Sharpen > Unsharp Mask

150 - .4 - 2 > OK
7. File > Save As

format - jpeg > Save

quality - 10 -maximum

format option -baseline (standard) > OK

That is perfect, except resolution 72 doesn't matter. Only pixel dimensions matter.
