How Do You Reduce Photo JPG File Size?

I go into paint and resize. I don't know about a MAC?

Make them into a pdf?

Use a photo editing program and either reduce the color resolution (8-bit, 24-bit, etc.), the resolution (number of pixels per inch), or the actual size. Most editors will let you see a preview before making the change.

Gimp is open-source and available for MAC platforms.

Many (if not most) picture editors (and some picture viewers) also allow you to change the jpeg image quality (or compression, since it is a compressed picture format) allowing you to reduce the picture size.

Not sure about the MAC. Try opening the picture with a picture editor you have, there should be an option for image quality or compression (probably under the options available when you "save as" the picture).

Mac is very easy. This is in Snow Leopard, but it will be very much the same in tiger or leopard. Go into iPhoto. Import your pics there if not already there. Click on iPhoto at the top. Go to "preferences" In General see there is a "Email photos using" Select the e-mail program that you use like Entourage or Mail. Then select the photos in iPhoto, at the top go to "share" then "Email" A block will apear choose small, medium or large. Medium works well and large is good for quality, Large is not full quality but good quality. then click on "compose message" In the event that your entourage or mail is not set up, like you are using yahoo or g-mail direct for example, you can just do it like I explained anyway but then in stead of sending the mail you save the attachments that the iPhoto created in that mail message to a folder on the desktop.Go to the attachments in the message under constuction. Select all of them and go to "save" Then re-attach them out of that folder. I just did a test. A pic that was more than a Meg became 90Kb in "medium" but the quality is good enough to see and the pic is not too small in size. Trust me, this is the best way to e-mail pics from a mac. You can instantly downsize lots of pics in one click and no editing noncence. Let me know how it went.

See if you can find an app called "packJPG" (http://www.elektronik.htw-aalen.de/packjpg/). Comes in a MAC version. Note that jpg is already compressed, and you could well lose some quality with further compression...

convert jpg to bmp, tiff or gif

I do it in Photoshop elements. I'm in LA. Email me the photos (you know my email) and I'll do this tomorrow night after my presentation is done and we are set up in the next hotel with email milo

Post the photos online, photo bucket or wherever, then you just have to send the link.

Most picture editors/ manager have option to resize the picture. Microsoft picture manager has the option to resize the picture to 1024*768, 800*600, 640*480, 448*336, 314*235, 160*160 or custom width*height or percentage of original width * ht pixles. Different as chosen will have different file size. I am sure there will be similar editor for OS as well.

If you have a graphics utility to open the jpg you'll have a 'resample' feature that will show the size and dimension of the jgp. By lowering the % it effectively makes the jpg smaller. Just remember to 'save as' (add a letter or two) if you wish to keep the original jpg. You will then have a copy of the smaller size and the original.

Do it for free with Irfanview: http://www.irfanview.com/

I use microsoft office picture manager. It came with my computer and is very easy to use.

Multiple Image Resizer allows you to process single photos or batch-process entire folders of photos. It will also convert between most common formats (jpg, gif, wmf, bmp, tif, exif, etc.). I found it while looking for a way to convert jpg's to ico's to make custom icons.
