Change Picture every 1 minute

[pribl]

display resolution of my macbook 1680x1050. I like to use "Change Picture every 1 minute" with my big collection of wallpapers ( size from 1024х768 to 4592 × 3016 ).

question : mac os x do not like to use some big (7 mb) and small photos as wallpapers ? wallpapers with small(big) dimensions ?

File size has not something to do with Mac OS X not using images as wallpaper, in my experience, but if that is the case, you could batch convert them to "smaller" JPEGs if necessary.
Dimensions are also not that big of a problem, I use wallpapers with a variety of resolutions (1280 x 800, 1680 x 1050, 1920 x 1200, 2560 x 1600).
Maybe batch convert the big ones to a smaller resolution, as the big resolution is not needed.

I guess you already selected FILL SCREEN?
