Hi, I have searched this forum and the max help - and I can't seem to figure out how to fallback to the specified label in a button if an image doesn't exist.

For example:

button foo "label" images:#("dcybtns.bmp", undefined, 1, 1, 1, 1, 1)

If dcybtns.bmp doesn't exist I would like to avoid the compile error and just use the text label instead.

I could check if the file exist before in a if/else clause, but I was thinking there had to be an easier way? I couldn't get try/catch to work either..

that's probably easiest way:

rollout test "test"
(
local images = if doesfileexist (getdir #ui + "\\icons\\dcybtns.bmp") then #("dcybtns.bmp", undefined, 1, 1, 1, 1, 1) else unsupplied
button bt "button" images:images
)
createdialog test

Thanks Denis, what if I'd want to check against the folder the script is executed from?

use getFilenamePath (getSourceFileName()) to get the directory of the loading script
