Ray, I think you're on the verge of using the wrong tool for the job. I think your needs might be better served by RevBrowser than the HTMLText property of the fields. First of all, that span tag will be worthless in the htmltext, it will just be ignored. Other thing is that HTMLText is not HTML and thus does not possess the necessary stuff under the hood to make things like image manipulation or introspection possible. I don't think you can check how wide or how tall an image is inside a field if the imagesource is set to a remote location. If you'd use a revBrowser window, it might be possible to check that data with javascript. If you just use the HTMLText thing, I don't think it is possible but I am not an expert, someone here might know better. 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.
