what is (i) in your code
you should use Index from

Sub ZGV_PanelRequested(Index As Int)
.......
LoadBitmapSample(File.DirRootExternal, ml.Get(Index) , ZGV.ItemSize,ZGV.ItemSize)
.......

how to resize ??? the items

items size are automatically calculated depending on how many items per row

if you need to resize items height you can use this instead
