Images are not permanent with new ACRT 3_72025

[raebened2]

Please advise why none of the images I load are there when I reopen the file. Sometimes they are there. Sometimes they are all gone. I thought maybe it was because some had spaces in the file name, so I took spaces out. Is there a file size limit? The JSONs that save the images are much bigger, maybe I'm pushing the limit with 6 or more PNG files?
Thanks!

Currently system does not support multiple images at once, you need to add child per image.
