alrite vijay_7287, as warrior mentioned, making a zip file is the better and easy way. I assume you have windows xp installed. Here's what you have to do:
Step 1: Right click on the folder/directory which has the pictures. If you haven't put the pictures in a separate folder and they are in "My Pictures" then just select the pictures you want to send and right click on the selection. I hope you know how to make multiple selections. (Try clicking with CTRL pressed to add to your selection and then right click over any selected file.)
Step 2: Move your mouse to the "Send To" option on the right click menu and select "Compressed (zipped) Folder". This will use windows inbuilt file archiving system and you should get a zipped file. In case you don't see it scroll down to the bottom of the window and it should be the last file.
Step 3: We're already done with zipping the file, yippee! Now all you have to do is attach it to an email and send it to whoever you want.
