* File Format: JPEG (.jpg)
* File Size: No larger than 150 KB.
* Dimension: No dimension may be shorter than 160 pixels or longer than 640 pixels.
I'm working with paint shop pro 8.1
I understand how to resize a photo so it's 640 pixels on the longest side, but I'm having trouble understanding how to change the file size to 150 KB.
The only why I know how to make the file size smaller is to keep changing the dimensions of the photo.
How do I change the file size to 150 KB and keep the dimensions at 640 pixels?
Thanks,

| When saving in JPEG, there should be a quality/compression option (one of the two) somewhere on the "save" dialog. Adjust that up/down as needed to get just under the 150KB. |

in PSP7. when saving, after you have selected JPEG as the file type, a button to the right "Options" (which is normally grey) becomes clickable. click that and your on your way to success!

Save as JPEG, but before saving, click on "Options", then click on "Run Optimizer". The number next to "Compressed:" is your file size. Set the number next to "Set compression value to:" allows you to reduce/enlarge the file size. Compress the file enough so that the number next to "Compressed" reads somewhere close to 150 KB. Click "OK", then "Save" (make sure you don't overwrite the original if you're not working in a copy).

Wow, fast replies :)
Got it resized, thanks!
I see a option "Save Exif data (only available with Standard format) in the resizing window.
When I check the box for this option it changes the file size from 150K to 204K
Do I want to leave this option checked or unchecked when resizing?
What's it doing when I check the option?
Thanks for all the replies, |

| Leave that UNCHECKED for entries. EXIF data is only required if you have to submit the original file -- never on the entry file. As you see, it wastes space! |

Great, many thanks!
Just one more question, maybe. :)
In the save options there is Encoding with Standard, Progessive and Lossless.
I would want to pick lossless, correct?

Exif is 54k of data?
I save in PS 7 with SAVE AS and leave the exif and do a file size of about 120-130k. I have tried Save For Web and picking 147k - it leaves out the EXIF info. I see no differrence in end quality.
Over at Fujimugs the 150k limit is hte same, but there you have to have the EXIF in or else it will be kicked (for date verification) and images there run to 800 pixels on a side. No quality issues there.

I'd think stadard. JPG is by definition a lossy file standard. I see no way to compress it and NOT have a loss.

There are several varieties of lossless compression, including LZW (used with TIFF files) and the Stuffit and ZIP formats used for archiving. There may well be a JPEG setting for lossless compression, although I always assumed there was always some amount of loss as well.

| If lossless is still under the file size limit, go with that. Jpeg compression that is lossless just writes the data in jpeg standard, without taking bits out. The translation may lose data, but the bits are still there. |
