Transparency?

I'm very new at creating filters, there are still many components that I don't know what they're used for exactly, how they affect what I do and I'm sure there's tons of things that I should probably do differently to have a more efficient filter... I've been working on one that I submitted this afternoon, I don't know if it will pass or not but there's something I would have liked to do with it and had no idea how. Here's a sample of the filter I made:



What I would have liked to do is make the "glass" transparent a little so that if it was applied over an image, the image would show through a bit, but leave the mortar opaque? I've seen some filters that do something somewhat like this, I've opened some of those in the filter editor to see how it's done, but ugh... there are so many components in there I couldn't figure out what did what... lol So I thought it might be easier to ask here... Is there a simple way to do this or am I trying to do something that may be a little bit too advanced for a gal who's only made a couple of filters so far? lol

Thanks in advance for any help!

ugh... I just looked in all the folders in program files/FilterForge so I could attach it but I can't find it anywhere... That's how noobie I am! lol

Thank you! It's not at all where I was looking for it... lol Here it is!

Take a look and learn how I used a switch to give the option of an image filter or not. I personally am drawn more to filters without that liferaft, so even if you have an option to do the picture visiblity, I would recommend setting default preset as the texture alone.
