What folder are the files in?   If you use the browser developer tools, what do you see being used for the URL that is being requested?

this the URL https://xxx.xx.xxx.xx:8898/ftds/view/view_custom_search and the image will be expected to display on the same page

this the file location in controller

    file_location = os.path.join(request.folder, 'views','Plot')

    plot_list = os.listdir(file_location)

this is in the view:

{{for r in plot_list:}}

{{ if r.endswith('.html'):}}

<div class="plot_path" id ={{=plot_list.index(r)}}  style = 'width:100%; height:500px; display:none' >

</div>

{{pass}}

{{pass}}

</div>

the HTML file is displayed on the same page correctly but not the images (it's blank) even though they're both in the same folder.

Please help, Thanks

I'm specifically interested in what the browser thinks the URLs are; you seem to be using relative URLs in your code, and perhaps the IFRAME() helper and the IMG() helper compute that differently.  Although I would expect you to need 'Plot' in the URLs for both.
Are you using routes.py at all?

PS:  A quick look at gluon/html.py suggests they both just set a tag and call DIV().

you mean src = _Plot/r ?

well, something like _src = "Plot/" + r

(URLs always use '/', so you don't need to do an "os.join()")


And I'm still interested in the browser's reading of the URL.  Perhaps you can use the devtool's "Inspect Element"  to grab the <A> tags and post them here.
