Thanks, David, that was too quick. I already tried it, but the script won’t work if a number contain commas. So, I have to remove it first. Second, the sub-dropdown is disabled.

However, I tried to add some code to the script to remove the existing commas:
app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.findWhat = ',';
app.documents[0].selection[0].changeGrep();

…and then I enabled the sub-dropdown list by commenting the line so that I can select:
//enabled = false;

Now I can say the script is working fine. However, I think that the dialog box should not be there and I can figure out that the actual working code lies in this area. I tried to tweak it but didn’t get any success.

var D, E = "", G, X;
D = decimalDropdown.selection.index ? "," : ".";
G = delimiterDropdown.selection.index ? "\u2009" : ",";
D == "." && E = "";
X = "d+"+E+D+"{0,1}d+";
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = X;
var myFinds = s.findGrep(), f, n, t, d;
while (f = myFinds.pop()){
n = f.contents.toString().split('.');
// Add commas to thousands
if (!ignore4.value || (n[0] && n[0].length > 4)){
t = n[0].split('').reverse().join('').match(/.{1,3}/g).join(G).split('').reverse().join('');
}
// Add commas to decimals if there are any.
if (!ignore4.value || (n[1] && n[1].length > 4)){
n[1] && (d = n[1].match(/.{1,3}/g).join(G), t += D + d);
}
t && f.contents = t;
}
}

Apart from this, the code also converts any numbers be it phone numbers or a year. It will be good if the script can sense numbers that starts with a Dollar($) or Pound(£) or Euro(€) symbol.

Thanks Jeremy. It worked as you said.

I didn’t realised that earlier.

Thanks a lot.

PS: I’m unable to give time to this forum for a long time. Really sorry about that. I’ll be back once things settled down.

Hi Qing, Hi Robert,

First, please accept my sincere apologies for not responding to your replies. I got stuck somewhere and couldn’t got the time to test these additions.

My initial requirement was to fit all the inline images in the story in the selected text frame. I tested both the scripts given by you (Qing and Robert) and they worked well.

Qing’s script was fixing all the inline images of the selected text frame but not in the whole story. I didn’t realized that Robert’s script was in fact fixing all the inline images in the whole story of the selected text frame. Secondly, to center align the inline images was an optional thought, which I fixed by updating the para style for the inline images.

Qing, your changes to the script worked the way I wanted:
var allRtg = myObject.parentStory.rectangles.everyItem().getElements();
This helps me fix all the inline images within the story.

Robert, your first script as I said worked well. The new updated code gives me a new thought as the new code was fixing all the inline images within the document. So I have saved this as a separate script for future requirements.

I must say, that now I have three scripts:
1) Fix all inline images within a Document.
2) Fix all inline images within a Story.
3) Fix all inline images within a TextFrame.

Thanks a ton to both of you :)
