What size are the icons in AppleScript dialogs?

Seems I missed all the relevant google words for this question. ~:-/ I just want to embed custom icons with “display dialog” (in an Xcode project, if that matters) and need to know the right size. Thanks for your help!


the size of the icons in Tiger is 128 x 128 pixel, in Leopard 512 x 512.
For the display dialog command 128 x 128 is sufficient, maybe even 64 x 64.
Consider that for AppleScript Studio the icon must be a TIFF image

Ah, thank you. The TIFF would have got me…


Update for the next ones looking for that answer:
72x72 for “display dialog” works best.
