Settings there are not very many, the most important are probably playing sequence, which can be set to "random" and Interval how often the picture is changed. The last is from 5 seconds to 1 hour (might have 1 day left conceivable).
Then you can also set special effects such as sepia or black / white, which personally is not used with me.
Mir is positively noticed that the picture frame well get along with images that have been recorded in much higher resolution and this is without any problems. The scaling down, so works automatically and you do not prepare his paintings especially for this picture frame. The main thing they are in JPEG format and have an ending JPG or JPEG.
Remote control would you probably use for initial setup and then when the images on the memory card exchanges. Otherwise it is unnecessary. If I would like to see proactive pictures, I take my laptop or sit in front of the TV or monitor.
Picture Frames has mE another purpose - play pictures in front of him. And you look it occasionally and would be again over another image. In addition, I found the response time of remote control something bad.
One should keep in mind that you "sacrifice" for the photo frame a memory card or a USB flash drive must. I once had an old 1GB SD card, where I draufgeladen 200. I think it's perfectly adequate. A 1.2 or 4 GB SD card you can get for a few Euro incl. Shipping and is therefore not worth mentioning and is sufficient for a few hundred images.
