cheers mate...

sorry did not get time until just now. i did as per what was told in your link. That does reduce the pixels. what i wanted to do was to reduce the size of the images. there are 328 images, total 498 MB...i thought if i can reduce the size then i can carry them around in my pen drive coz all the images are JPEG/JPG.when each one is opened with MS paint & just "saved as.." the same file name..overwrite/yes..then the file size reduces automatically..i hope you can understand me. how can i reduce the size..thks lots mate

PS : by the way the original dimension (dont know what that means) of each foto/image is 2592 x 1944
