What picture frame mockup app do you use to automatically place your digital images into?

[PlanetArtPrints]

I currently use Placeit, but they have a very limited number of picture frames available with even more limited aspect ratios.  I've still been mostly placing my images into frames using photoshop, which is incredibly time-consuming.   Is there a better app than Placeit I can use to expedite the process?  I really haven't seen many mockup websites that are great for placing images into picture frames; they seem to be mostly for placing images onto clothes, coffee mugs, etc.

I want to speed up how fast I can list on etsy as much as possible.  Thank you for any assistance!

I use Canvy.  I've tried ArtPlacer and PlaceIt.  ArtPlacer put my work "too far away" in their pictures, but I liked the customization of the frames.  PlaceIt had nice "close up" photos in frames, but that meant my work needed to be in the same image size as the mock up, so that required extra steps but I liked how it displayed my work using 8x10 mock up for example.  With Canvy you don't get that close up detail, but you can customize the frame and dimensions.  I've looked into the PSD mock ups but I use Gimp which doesn't easily translate.  One of these days I plan on diving into more though.  So, at the moment I'm going to stick with Canvy.
