Hi Jonathan,
Cool.
Works a treat and no need for array.
Using a percentage also means I can allow the browser widget to be resized.
Very cool.
img {
Max-width: 90%;
}

Hi James,
Just a quick note - you can set the max-width of images in CSS. That will limit
their size with just one line.

It sounds like the dataURL method costs about a tenth of a second per image,
for moderately large images.
I had never tested that, but it's good to know. For my purposes right now, that
is not an issue, but it could be for plenty of situations.

Thank you so much Hermann and Jonathan
It took me a little time but I worked out what to do after looking at your
suggestions.
The fact that setting the htmltext of the browser widget breaks the img URL's
makes sense from a security and logical point of view.
I then tried Jonathan's technique
An option for James could be to put ONE html-file in the images folder
with content:
And then set any image of that images folder by changing the HTML by
javascript:
on mouseUp
put "flower2.png" into nn -- give the name directly
put line 42 of myImages into nn -- a list containing the image
James - if you look at the example stack on LiveCode share "browser widget
image manipulator" it has some LC code for creating a dataURl for an image.
Use that to create the data URL for the image.
Basically:
Get the image info from the image file like this:
Put URL "binfile:imagepath" into

No. I wrote this only because the example used a relative path pointing to the
same folder:

So - thinking about this dime more - the browser widget uses a dummy URL if not
told to load a specific URL, and the dummy URL would not have permission to
access local drives, for security reasons.
That would mean the "file:///" prefix would not work either.
So he would have to either save the
Hi Hermann,
Is this part of the same-source policy for web pages? The HTML file and the
image file needing to be in the same folder?

One other solution...
You can convert the image source to a data URL. You can construct the htmltext
for the dataurl in LC, and replace the current image SRC information with
dataURL SRC information. Then, when you set the htmltext of the browser widget,
the images will show up without needing
Hi James,
Can you post an example of your actual filepath?
With HTML, the first part of the path to the local disk usually looks like this:
"file:///C:/users/pictures/mypicture.png"
LC should be able to give you the right full path to a document- but make sure
to try using the "file:///" prefi
You can have that without a (local) server when using a browser widget.
Although you can NOT display an image from disk without javascript by
only setting the htmltext with a correct filepath, for example as follows.
(This is a browser engine thing, can not be influenced by the widget.)

You have to set it in the HTML, with HTML-syntax.
LC Script may help with that by sending the imagedata to the HTML page.
Examples how to do this can be found (look at handler "chooseScript" in the
card's script and make the widget or revBrowser display visible) as follows.

Can someone tell me the correct format for an image src tag to use with the

I have a folder of HTML and an associated folder of images yet I am unable to

They are .png.

Src = "relative path to image"
