Sadly, I’m only just learning how all this works (though I make and use vbs, bat and reg files to add & remove functions)…just see that the pieces seem to be out there and a simpler, more cohesive way to get eBook covers in Explorer seems doable. I’ve been researching this around the web for a while and ask here because it seems that a reasonable collection of Handlers existed in Sumatra source at one time and Sumatra itself isn’t updated often with feature requests. The whole thing could coexist as a separate “eBook thumbs” installer from Sumatra in the same way Sage Thumbs exists separate from graphics programs. The same handler installer would be helpful for installed version of Sumatra (forgotten during Sumatra install, handlers get messed up in new Sumatra builds or handlers get messed-up by other program installs). But an UNinstaller could be included to clean the system of these handlers (in the same way I can easily uninstall CBX Shell and Mobi Handler with common Windows uninstallers). I understand that this Handler Installer doesn’t qualify as “portable” in that it writes to Registry to enhance Explorer. So I’m just wondering if the actual “handlers” (dlls?) are floating around here or can be collected from other open sources and resurrected into a separate Handler Installer.
