Same here. I bought Designer from you guys some months ago and I'm a happy user, so I thought I should go ahead and buy Photo as well. Sadly, I realized the long standing offer for 25 USD had expired and 50 USD seemed a little too much for me as I rarely deal with raster images (yeah, I know it's still a bargain for most people). I ended up searching for offers or coupons, I thought maybe someone bought it in the 25 USD era and could be willing to sell it.
Anyway, long story short, I ended up on ebay.co.uk, to a listing advertising "genuine license" for 3.5 GBP! I bought it and I received a download link for the software, which included Photo indeed but in a very odd setup. The application was repackaged with something called "Turbo.net" which I googled and found to be legitimate software. Apparently, the seller bought one copy from you, she/he installed it on their computer, and used this Turbo.net piece of software to create a sandboxed package that can be deployed on other computers.
After googling, I didn't even try to run, so I don't know if it runs eventually. I told the seller that this is piracy - he disagreed but upon insisting he did return my money. I see at least one review of his "shop" with a happy customer so I think this package might actually work.
His shop is still active, and I still have his Google Drive download link if you wish to investigate.
