i have taken some pictures with my dad 4.1 mega pixel camera, and the thing is, an image which is a j-peg, is like 1.69MB :O is there any software that can compress them??
JPEG is already compressed by nature. Since JPEG uses a lossy compression method, the more you compress an image the more image information is lost and image quality suffers. If you want the files to be smaller you can rescale the image smaller, use higher JPEG compression, or even a different format. But if the images are important at all, you should take care to preserve the originals 'as-is', making down-scaled copies for whatever purpose you would need smaller files.
Best bet is to open it in photoshop..resize it to however large you need..usually digital pics are around 1600x1200..which can easily be resized to 800x600 and no one would notice..this will knock off a huge chunk in file size. Also when saving, you are given the choice of quality..save it around 7 or 8 will help with out noticeably removing quality, and finally, open the jpg in paint, after processing in photoshop. Save it as a jpg, and the file size will decrease even more, with no change in quality at all.
4 megabit is huge resolution for simple pictures of your rig. You can use your favorite photo-editing software to scale the image down to an appropriate resolution for your purposes. In your case, something between 640x480 and 1280x1024 would be reasonable. Pehaps 800x600? Crop the image if necessary.
Hi Not sure if this is of any use to you but here goes: In most recent cameras (like the one I have just purchased - Canon A520) you can preset the resolution of the picture which should save you some work later on (downresoluting). I am not sure which camera you have so I can not comment on this one.....
