Please...
Hello, I am new to this wonderful site and would love to submit a photo in the Glass open challenge and have had two rejections.
The first one was an 8 by 10 with 1440 x 1800...found out waaaay too big. (My summary also showed 180 by 180 and I didn't know which applied). Second one I tried to photo size pixels and think I had it okay, but after submitting I got an "You caused an internal message error." Obviously, I don't know what I am doing!
Is it possible to help me or am I beyond help?
This is a Great Site. Many great photos! Thanks, Marjo

Hi Marjo

Welcome aboard!

Please read The Rules and that will be a good guide for you.

Hello marj,
Welcome to DPC... You're certainly not beyond help, everyone started where you are at one time!
It would be helpful to know what software you're using for editing; I'll give examples of resizing for Photoshop and Irfanview. The latter is a freeware program in case you want to download it.

For PS 7 (ass-u-ming windows OS):
With image open, right click on the image title bar, select "Image Size". the dimensions in pixels are given in the top two boxes. Make sure "constrain proportions" box is checked (bottom of pop-up), and that the resampling option is set to bicubic. in place of the larger of your two dimensions, type 640. the other dimension will be automatically updated to the proper number to maintain proportion.
Now choose "File/Save" and set type to JPG if not already, then adjust quality slider to obtain largest file size that does not go over 150k. You can use "Save for Web" for more control, but try the simple approach first.
Now check your file on disk, it should be under 150k. You're ready to submit.

In Irfanview, open your image, do your adjustments, then choose "Resize/Resample from the "Image" menu. Enter 640 as replacement for the larger number, make sure "resample" radio button is checked, choose "Lanczos filter" as resampling option, and click OK.
Save file; there is no feedback on size, so you need to start high, and work down until you are below the 150k size limit for submission. Save each as a new file name and use the largest that is under 150k. Remember to choose JPG as type (don't choose JPEG 2000).

Hope this helps...Kirbic

Thanks for the welcome, Kosmikkreeper and Kirbic. Someday, I'll be able to help someone...How is that for positives?
Okay, I am using an (older)Adobe program and I think it is similar to what you have described, but...I now can't even find my saved copy. I am going to restart and see if it is there and if not...start over.
After getting my pixels correct, the resize was odd, 8 by 6 or something?
Thanks for responding and any additional input is appreciated. Marjo

Yup, if you resize to 640x480, your aspect ratio = 480/640=0.75, and 6/8 is also 0.75. Since your size in inches is listed as inches in the long dimension, and you have 640 pixels in the long dimension, your print resolution would be 80 pixels per inch, or 80 dpi (dpi = dots per inch).
Note that by the rules, you can crop to any aspect ratio, not just 0.75. For instance, you can post a square image (aspect ratio of 1.0) with a maximum resolution of 640x640. Your smallest size must be at least 160 pixels, but any combination of width and height within these bounds is acceptable.

Thanks kirbic. I'm following along pretty well... but when I keep my resolution for clarity, my resized photo is only 1 by 2 inches approx!
So now I am more confused. I may be beyond hope, afterall.
I appreciate the time you are taking to help me.

I think you need not worry about the inch size----only the number of pixels and the 150mb maximum file size.
