| I'm still new and am having trouble with size. I see peoples submissions and they are these big beautiful detailed shots. As I try to submit mine and meet the 150k requirement, I end up with not much more than a thumbnail. I have tried in photo shop "save for web", and optimize for file size, but it is still kind of small and when I go to submit, it ends up still too big (the size jumps around in different programs). Any suggestions would be well appreciated :-) thanks. |

Use save for web, adjust the longest side of your picture to 640, then use the jpeg slider (compression) to adjust the image down to about 145KB.
That seems to be what most people do, anyway.

After you have edited and cropped the pic (when you are done) then Resize it to be 640 pixels on the long side (top or bottom if a wide shot, left or right side if it is portrait style). After resizing is when you should do your sharpening (UnSharp Mask - USM), as resizing can soften a picture.
Then go to SAVE AS and choose JPG. Not sure what editing program you are using, but the 2 or 3 i have used all will igve you a choice of compression and an estimated file size at this point. I use Photoshop and compress most of my entried in the 9 or 10 (on a scale of 1-12). That makes them 120-140k in size. I then upload that file.
Compressing below 8 or multiple times will degrade the quality of the picture.
Many folks use the "save for Web' - whether it is for convenience, concerns regarding web safe pallette issues, or irt works for them I cannot say. I have never used that method as I don't know what it does - I like the control of the Save As - I know what is happening and have control over it.

I like the ability to choose an exact percentage of compression with the save for web option. I can then save my shots with the minimum compression needed to get below 150kb

Save for web actually gives you a little more control, sice it gives you your file size as you move the slider - no estimating. Other than that it's the same as far as I know. |

You have to resize your image and then compress it. Here is what I do. I use Print Shop Pro, but it is probably pretty much the same in other packages. First select Resize (under the Image menu), this will allow you to select size of the images in pixels. The rules specify that your image must not exceed 640 pixels in height or width.
The resize option will allow you to resize in pixels, inches or centimeters, pick pixels. Make sure the "lock aspect ratio" box is checked and then change the height and/or width to match the size you want. Click OK. Your image should now be resized, next you have to save it and compress it to get under the 150K limit. I click on the JPG button where it lets you set the compression level while simultaneously showing you what the ultimate file size will be along with a preview window so that you don't compress it too much and lose detail. Hope this helps. |

I had trouble with this at first too.
Here's what I do:
1. In photoshop open your original image
2. Go to Image > Image Size
3. Ensure that all three boxes at the bottom are ticked, and then
at the top - where it says pixel dimensions, change the largest
number (either height or width) to 640 and click OK.
4. Go to File > Save as and rename the image to whatever you
like (eg 'image 132 compressed for web) now click Save.
5. A box should appear with a sliding bar - shift this around
until you get the image under 130k
6. You're done - click on the zoom tool and 'actual pixels' at the
top to see how the image will appear on DPC. It shouldn't compare
too badly when viewed at that size.
- I'm not sure about 'Save for web', I personally find this method
simplest.
- It seems a strange quirk of photoshop that you can save an image as
146k (for example) but windows shows the file as being 170k
Don't know if anyone else can explain this.
A trick I use is to save the file as close to around 170k as possible,
and then open it in Microsoft Picture Manager. I crop 1 row of pixels
from one side and resave the image - for some reason this knocks
about 20k off the image size. |

Actually, the great thing about "Save for Web" with Photoshop is that it allows you to preview - side-by-side - with the original so you see what different settings will look like. There have been instances where I've opted for a smaller dimension in favor of less compression, just because it looked better. |

Having played around with Save for Web - it looks like the best
system to use, it eliminates the problem of the inaccurate file
size and you can be more precise |
