How do I make a picture smaller?

Actually you can reduce the file size without making the picture smaller. One way to do that is using the jpeg wizard. This is available online to try:

If the image is a gif file, gifoptimizer can do the trick.

My bet is that file size is much the issue (and perhaps THE issue) on My Space. I recommend Irfanview (picture viewer/manager)from www.irfanview.com (free, but outstanding).
I frequently use the "Batch Conversion" feature to quickly reduce file size and/or resolution for email purposes. A 1-2MB picture file can easily be reduced to a 100-200KB file (or smaller).

perhaps easiest of all for the novice is the Windows Power Toys Image re-sizer - after install just right click on the image and choose "resize picture(s)" - only 4 choices for size but they should cover most situations just fine and it does an admirable job reducing file size without much quality loss...automatically resizes and renames (leaves original intact) in the same directory...very handy and quick...at:

If you just want to resize the picture as per view, load the picture into your editor (WYSIWYG)click on it once. Then while holding down the [Shift] key, click on the bottom right handle in the bottom right corner and drag toward the center of the picture. Holding down the [Shift] key will maintain the object's aspect ratio. Then save and upload to your server.

I would LOVE to see how to do these things, but for Mac OSX... I'm having an impossible time even doing simple things like saving the image as a smaller file in Photoshop. (NO paint for Macs).(Nothing that useful or simple from the 'user-friendly and simple' company).

For Mac OS X users, there is a program called GraphicConverter ( a shareware, bundled with many Mac CPUs), much easier to use than Photoshop and making all file-size/image-size manipulations (and much more) in very simple way.

Thank you sooooo such... I got what i needed to get done without having to spend any money and i had the programm just did not know how to use it.....
I learned something new today thanks to you..
thank you renee

Thank you, thank you, thank you. I've done resizing but found it cumbersome. This is my first intro to Paint and I find it just lovely... It will assure that the sizing is correct, without by having to guess or use Photoshop.

this makes no sense i just want my pic less than 5md..i don't know jack about compression reslution etc...this is not user friendly..give me a site that says reduce this pic to 5mb

GENIUS!!!!!!!! Thankz!!
