Hi Community Expert,
Currently, I'm working on one project in that I want to give custom alt text to 100+ images mentioned in the caption.
My current process is we copy the caption then right-click on the image and select "Object Export Options" select "Alt Text" -- Custom and paste.
Can someone help me with that how we can create a script for this?
Thanks in advance!!
No need to select anything, Mike. Look for anchored images, a return, and the following character (i.e. an inline image and the following paragraph). If the image is in an 'IMG - Figure' paragraph and the following paragraph is an 'IMG - Caption', then set the inline's alt text to the caption's content:
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = '~a\\r.';
found = app.documents[0].findGrep();
for (i = 0; i < found.length; i++) {
if (found[i].paragraphs[0].appliedPara

Hi @Shanpub, I think this can be done fairly easily so long as there is a reliable way to find the caption of the selected image. How is the caption built? Is it a Live Caption? Is it in a particular paragraph style? Can you share a one or two page indesign file with example image and captions please.

@m1b caption is not a Live Caption it's a static caption change for every image.
Yes, we use the "Image - Caption" Paragraph style. Please find attached the InDesign file.

Hello @Shanpub,
Give the below script a try and let us know if that's what you were looking for...
function GetClipboard(){
var clipboard;
if(File.fs == "Macintosh"){
var script = 'tell application "Finder"\nset clip to the clipboard\nend tell\nreturn clip';
clipboard = app.doScript (script,ScriptLanguage.APPLESCRIPT_LANGUAGE);
} else {
var script = 'Set objHTML = CreateObject("htmlfile")\r'+
'returnValue = objHTML.ParentWindow.ClipboardData.GetData("text")';
clipboard = app.doScript(script,ScriptLanguage.VISUAL_BASIC);
}
return clipboard;
}
myClipboardContents = GetClipboard();
var mySelection = app.selection[0];
if (app.selection.length == 0) {
alert ("Nothing is selected.");
}
else if (mySelection.graphics.length == 1) {
mySelection.objectExportOptions.altTextSourceType = SourceType.SOURCE_CUSTOM;
mySelection.objectExportOptions.customAltText = myClipboardContents;
} else {
alert('Error!\n The selection is not an image.');
}
Regards,
Mike

Hi together,
FWIW: Alt Text still is not part of the InDesign ExtendScript scripting DOM ( Document Object Model ).
Another one: Alt Text will be removed if you export to IDML and open the IDML file as InDesign document.
( Just a warning; you'll find a bug report about this at InDesign UserVoice. )
EDITED: Seems, that I had this wrong…

Apologies for not catching this earlier.
A graphic's Alt Text and caption should never be the same.
