Since most frames have limited on-board memory (between 128MB and 256MB) you will want to resize the image files to 1) match the actual frame image ratio and 2) save them at 72 DPI 3) saving them with just enough JPEG compression to keep the image files under 100KB
While you can view the larger 4.5MB files as you can see, you will only be able to store 25 to 45 images. Resized, it will hold over a 1000
Most modern photo programs allow you to resize in batches and rename the new smaller files|||10mp are roughly (very roughly) equal to 32x40 inches at full size. You%26#039;re not going to find a digital frame that big...sorry. Just so you know, downscaling will not reduce your image quality unless you get a bad brand, so I%26#039;d suggest getting a larger sized frame from a manufacturer of good repute, such as Canon or Sony.
