The bigger it is, the best it is! But be carefull, because the maximum size is 300KB, which is not that much. I will suggest you at least 1920x1080. If you can, add external gradient-to-transparent borders on the sides and the bottom, so if the screen-size become bigger, it will still looks normal. That means a little more than 1920x1080 (standard full-HD 1080p screen). So the bigger it can be the best it will be. If it says "the file exceed the limits", it means it's more than 300KB.

Now, to modify your picture (to reduce quality, for example), you will need to use aome specific software. I will suggest you GIMP2, which is free and really easy to use. You can lao save files in different format (jpg, png, etc.).

Hope I answered your question this time, if you need any further help I will be happy to help you ;)
