Reducing file size for e-mailing

    Hope this isn't a silly question but can anyone suggest how I might easily reduce the size of my photos to make them easier to e-mail. I do have HP image zone express which has an e-mail program on it but it just never seems to work. Always telling me to try again later. I'm a complete novice so any advice would be much appreciated.

    If your software won't email them just add the images as an attachment straight to the email normally using the paperclip icon. I presume they are already in Jpeg format. The trouble you are going to have is these types of file do not compress with zip etc... so you are limited with choices.

    ????

    if you want to make them easier to email, first download winRAR

    http://www.download.com/3000-2250-10007677.html

    then put all the photos you want to send into a folder.

    the right click the folder and click compress and email - make sure it is in the ZIP format (because the recipient's computer will automatically unzip them with a double click). and then hey presto

    Have you actually tried to do what you suggested?

    Maybe you should try and zip them and see what compression you are able to get before you suggest that action.

    A 432 MB file containing JPEG images compresses to 431MB using winzip, hardly enough difference to make emailing any easier!

    I am using Winrar, so have tried it with both apps, and using various levels of compression.

    Maybe there is a special setting you use for JPEGs, if so please let us know what it is!

    Read this before making statements that aren't true

    Jpeg files from a camera as opposed to RAW image, maybe you need to learn a bit about photography!

    (.JPG file extension, pronounced Jay Peg). This is the right format for those photo images which must be very small files, for example, for web sites or for email. The JPG file is wonderfully small, often compressed by 90%, or to only 1/10 of the size of the original data, which is very good when modems are involved. However, this fantastic compression efficiency comes with a high price. JPG uses lossy compression (lossy meaning "with losses"). Lossy means that some image quality is lost when the JPG data is compressed and saved, and this quality can never be recovered.

    How do you compress a file that by its nature is already compressed?

    my statement was true

    i know i dont know much about photograpy, but i was trying to help in relation to compression.

    and the fact that you say

    suggests that you were none the wiser than me initially, so.....

    The reason I say crap is because that is what you are talking!

    You can not compress a JPEG (FACT)

    The only way to get it smaller is to open it in a photo editing software and then reduce the quality of the saved image! (FACT)

    You are merely making a statement on what you think happens to any file if it is compressed. Yes if I Zip or RAR a PDF etc... it gets smaller.

    If I or anyone else that tries to compress a JPEG, nothing or little happens.

    Next time actually do your homework before you start jumping on what other people have said.

    Take some time, download some pictures from your digital camera if you have one and try and compress them.

    Next do a search in Google, and see what everyone who has tried to do what you describe, is saying about the results. Strange but the common response is that it is a waste of time and it can't be done to any great effect.

    You are the one starting to deride me with LOL all over your post.

    The sole purpose of these threads is to provide accurate information to people, which is what I have given. Not to just jump in without any idea of what you are talking about, presumably to just increase the ranking.

    Back to helping Jackeen!

    I'm sure you never started this thread to read our dispute over the usefulness of compression on JPEG images.
    If the software that came with your camera allows it, just open the picture and then save a copy reducing the quality.
    If it does not, then get a better photo-editing suite such as available from Adobe.

    Everybody needs to take a step back and chill out. Otherwise this thread may get closed and that won't help anyone.

    It's true that JPEG is already a compressed format, but that doesn't automatically mean it can't be compressed further. However, it's true that compressing a JPEG will not normally result in any more than a negligible change in size and it may actually end up bigger than the original. The fact is that any given (lossless) compression algorithm is based on finding large patterns of 1's and 0's that can be replaced with smaller patterns of 1's and 0's. Generally speaking, for any specialized format (like JPEG), particularly one that's already compressed, you need to come up with a specialized algorithm for the patterns inherent in the format. AFAIK no one has come up with such a thing for JPEGs. As a result there's no way to determine if you'll get any decrease in size when compressing and in many cases the size will increase due to the overhead of the compression format.

    Sorry if I got a bit carried away, I was initially just trying to help.

    Apologies to Lethal_B nothing personal!

    Jackeen, hope this has at least in the end, informed you how to change the size of your images for emailing.

    The best tool for downsizing pictures for email is the ImageResizer in Windows PowerToys. Can be had at Windows Download page. Works great.

    Well, what can I say, I now know far more than I did this time last week and it seems the solution to my problem is to get better software. Didn't mean for ye guys to get argumentative, however, not only did I learn loads but I had a good laugh into the bargain:)

    Cheers to all!

    I still think there is a way around this i do it all the time with photo's from my digital camera. I have a picture of my cat which from my fuji camera which its it current jpeg format is 584kb. What i do is to open in the picture viewer and then print screen it making sure the cursor is out the way of the main photo. Then open good windows paint and EDIT and PASTE into paint then using the square cut tool draw around the photo and nothing else then EDIT and CUT.

    Close paint then reopen it and EDIT and PASTE again and now you will have just the main photo again. Then file save as JPEG and name it. Then compare the photo's you will not see any difference except for the picture will be slighty smaller is size.

    The file size of original is 584kb
    The new picture size is now 81.5kb less than one fifth the size

    Try is yourself!
