Sorry - if Admin can maybe delete this, please do - found the problem.  I had the "cover" setting on, rather than the "%/%".  Sorted.  :)

Hiya

I'm still finding the Slider my toughest component to use at times with respect to getting settings right each week when it comes to changing a slide image.  While I can figure out most, the one item that frustrates me endlessly (partly as I don't note down previous settings) is what size of image fits the box perfectly.  Each week I'll resize an image down to anything from 750 x 400 to 600 x 300 yet the image refuses to fit into the box properly invariably always being too large so text at the bottom gets missed out.  Cue endless sizing edits and uploads but somehow the system then never seems to either replace the image properly (despite caches all being cleared each time) or something else is going on.  Is there a particular size of image to use and/or method of replacing to ensure a new image is shown correctly?  

Any ideas?
