Most picture frames have bitmap sizes of 800 x 600 pixels, which is a jpg picture of appr. 100-120 kb. Digital cameras easily create 4-6 MB jpg pictures. About 30-60 times the size you actually need for your picture frame. So, instead of 250 pictures you should have more than 7,500-15,000 pictures fit on a 1Gb memory card. With PictureFrame Wizard you will increase the amount of pictures on the memory card fully automated. And with the same visual quality: the size of the picture is optimized to fit in your picture frame.
