Ok guys. Time to ask for some help. I have a good crop of the image that I want to submit for the Fire challenge. The dimensions are within spec of requirements to submit for the challenge. The size, however, is not.
How can I reduce the size of my image in Kb without having to resize my image crop?
Thanks again! |

Make sure the Resolution is set to 72dpi, then when you save it as a Jpeg, you can use some compression. What editing program are you using? Let us know and someone can give you specific directions for that program.

The image is 640x368 @ 72 dpi. I am using Photoshop CS.
The image, in jpg right now, is 690K. |

| if you have photoshop go to file...save for web...there is a arrow right above the optimized check. click that and click optimized to file size. set your 150k in there and it will size it closest to that specific size.... |

Just a note: the size as displayed in the bottom of the window is always the actual, uncompressed size (as in a TIFF) and equals (640 * 368 * 3)/1.024
The 3 comes from the 8 bits (or 1 byte) per color channel/per pixel; the 1.024 to convert bytes to KB. |

I just had the same problem, but did things a different way.
I resized the pic(initially 1.2m) to a VGA using the camera |

Never quite understood why people consider DPI when targetting images for the screen. Resolution is completely notional when making an image 640px * 480px.. It doesn't matter what resolution you choose - it will STILL be 640px * 480px.
It's like buying wallpaper for a 12ft wide wall. You can cover it by pasting 6 * 2ft strips. Choosing 1ft wide strips doesn't mean you need less than 12ft's worth of paper.. |

Because if you open the image in Photoshop, it will display the image considering the resolution; 640 pixels will display 6.889 inches at 72 dpi, and a little over 2 inches at 300. This also occurs when importing an image into a layout program.
It is true that all browsers display at 72 or 96 dpi, but setting your resolution to the same as the browser's helps to visualize the final display while still in the editing program. |
