|
|
||
| Possible values for the `proxy` parameter are: | ||
|
|
||
| * The string `#{folder/}picturename` or `file:{folder/}picturename` if the picture comes from a file stored in the `Resources` folder | ||
| * A variable name if the picture comes from a `picture variable` | ||
| * ~~A number, preceded with a question mark (ex.: “?250”) if the picture comes from a `picture library`~~ | ||
