I think this is the only way. If you'd go with RevBrowser you could set image attribute such as height and width in the img tag but HTMLText does not work like that. Heck, I wish it was not called HTMLText but SGMLText or something like FancyTaggedText Actually you can do it this way: 1) Retrieve the image from the web into an image object. 2) Change the size of the image object itself, making sure to keep the dimensions consistent so you don't get stretching/skewing. 3) Lock the image object (set the lockLoc of image to true) 4) In your field, instead of setting the htmlText to the image with the ID of the image object in img src. Here's a simple example (I had to add a couple of returns before the text so you could see the bird - watch linewraps): on mouseUp set the lockLoc of img testImage to false set the filename of img testImage to set the filename of image testImage to http://linkit.com/Schools/ETS%20Items/ETS%20Item%20Bank/ETS10Q1/01%20Full%2 0Bank/04%20ELA%20QTI%20with%20GUIDs/Grade%20KLanguage%20Arts-95/images/38228 .jpg set the width of img testimage to (the width of img testimage/4) set the height of img testimage to (the height of img testimage/4) set the lockLoc of img testImage to true set the htmlText of fld 1 to (PPPHere's the bird img src= quote (the id of img testImage) quote ) end mouseUp Ken Ray Sons of Thunder Software, Inc.

RE: HTML Text and Images
Bernd, Works like a charm! Now, any suggestions on how to resize the image which is showing up when setting the htmlText of a field? This is a tough one, I know, and I don't think there is a way to do this. I just thought I'd throw it out there to see if anybody has any suggestions.

If you'd use a revBrowser window, it might be possible to check that data with javascript.

I think you might need to: * Rethink if HTMLText is what you should be using and maybe consider moving to a better hypertext container such as revbrowser (which is not a field and thus not really editable) * If you stay with HTMLText, then, you might need an auxiliary routine to parse the HTMLText property to pick all the images from the remote location, download them, manipulate them as needed and then use them in the HTMLText thing.

RE: HTML Text and Images
Andre, Thanks again for your input here. Jim Ault's suggestion is working well; that I create an image, set its filename to the image's URL to get the image's height and width and then delete the image. The only thing I'm really unable to do now is resize images. I'm not sure how I would do that going the browser route so I might just stick with the htmlText route. If worse comes to worse I can always just keep the image I create to get the dimensions, resize it and use it instead.
