There is a Gallery posted here Photoplog Lite which is free and for a freebie its damn good, there looks like a Pro version coming along to but thats unlikely to be free, but it does look like the prices will be pretty fair..

I know vbportal is paid but, aside from the cart and gallery it has everything in your list and lots more Dean_C, and again the price isnt a harsh like some other mods, you can also just not use any of the elements of it you dont need.

Im all for free and open source, but a donations button does not allways work either.
At the end of the day providing mods such as these is not just down to "here you go" as most required a reasonable amount of support dedication as well when your looking at mods of this size.
