Your photo editing software will do this.
Find the file you want.. say Snake Eyes IMG in My documents. Once you know where the document is. Go and open your photo editing software program and select open file.
Go to the exact location and click open. Next go to the Image Resize tool and resize the image to the size you want.
Some programs have the image resize on the top of the tool bar too, next to file/edit. There is an Image option. where you can buffer, posterize, resize, grayscale etc.
Once your happy with the image size just click save and try uploading the photo again in the relevant section of the forums.
