So now, here's how this problem is dealt with specifically on my system:

* After the system boots up, right clicking on any picture file for the first time slows down the right click menu because of OmniPage being in the right click menu. To remove OmniPage 15 from the right click menu, remove all opshel15 registry entries. If previous versions such as version 14 were installed on the system previously, remove opshel14 entries etc. as well.

So in my case:
Start Menu > Run... > regedit > OK
Scroll up and click on My Computer > Edit > Find... >
opshel15
Delete all opshel15 entries. (Press F3 to find next opshel15 entry.)
Delete all opshel14 entries.
Delete all opshel12 entries.
Also found this bit of info at PCreview.co.uk forums

If the installer cleanup doesn't do it; try this:

Depending on what version of omnipage that may have been installed at one point, these opshel entries my remain in the windows registry. Try opening start|run|regedit, then make a backup of your registry by going to the regedit file menu and select "export registry file" or something like that; once you have your registry backed up, click on the top of the registry tree "my computer" then go to the edit menu, click on find, or just use CTRL+F, then type in opshel then click search, delete the entry, find next | delete entry, do this until you don't find anymore opshel entries. Once you have them all deleted, exit regedit, then reboot.
