In the TM ART Monitor Workbench see this function:
WEB_OPT_AUTO_LOAD_IMAGES - Enables the automatic downloading of embedded images. Set nValue to 1 to load the images, or to 0 to not load the images. This option affects the page-based browser-level functions. This function overrides the Automatically load images option in the Emulation category of the Web profile settings.
Thanks Dan. As I was reading your Answer I found mention of this in the Help tool for Workbench.
Have a great day!
