I put two images up for round and temperature challenges that were way too small. I then figured out how to rer-size with Adobe PS Elements. I have successfully uploaded an image into the Contrasts challenge but I can't get the site to accept my entries for the next two challenges. They are too big, but I am doing what I did for the Contrasts entry. I am in despair! Anne

There are 2 reasons why your photo is being rejected that i can think of. One, you photo is bigger than 150kb or two, you photo's longest side is greater tha 640 pixels. Open up your image and go to image size, check the document size width and height are set in pixels and manually change it to 640 if it is above that. Save the image, but keep the original and check how big the image file is. If it is under 147 kb than you are set, if it is above than you may have to change the image quality to get it down to under this amount.

These are the steps I go through when resizing my photos for challenges. I also use Photoshop Elements.

1. Make any color adjustments etc that I want to make.
2. If I want to crop my photo, I crop it to the shape I want.
3. From the menu, select Image -> Resize -> Image Size
4. Make sure the Constraint Proportions and Resample Image Bicubic are both selected.
5. For the width or height field (whichever contains the larger value) enter 640 (or whatever length you want the longer side of your photo to be). 640 is the max. allowed on DPC. Click OK.
6. The image should now be much smaller. Select View -> Actual Pixels to see it at the size it will display on the website.
7. Filter -> Sharpen -> Unsharp Mask ...
8. Set Amount = 50, Radius = 1.0 and Threshold = 0 (or adjust the numbers to your liking), click OK.
9. The image should look just a little bit sharper, but you shouldn't see any "halo" around edges.
10. File -> Save for Web
11. Adjust the number in the Quality box so that the size displayed under the image to the right is slightly less than 150k. With most images, a quality of 80 is a good starting point. Adjust quality up or down as necessary to get close to (but not over) 150k.
12. Click OK.
13. Save in the directory and with the name of your choice.
14. Submit to DPC and nervously wait for voting to start ;)

Good luck :)

FranziskaLang's explanation is great, but if you're going to be in the "Save for web" window, might as well get rid of the "quality" guessing, and click the little arrow above the quality number, and go to "optimize to file size", and set something like 147k (just to be sure you're not going over the 150k limit). Press OK, and it'll calculate the quality needed to stay at or below that file-size. Click save and you're done :)

That is a great tutorial ... should be a link to it in the tutorials section. I'm sure it would very useful for some new users.

Those responses are all helpful and if you see entries from me you will know I mastered it with your help. I also agree that they would make a great tutorial...I looked for one and wished that there had been something. Thank you all. Anne
