A few observations - constructive criticisms, intended to help you refine the deck into a better version of itself.
The spot card 8 of Spades looks fine - if you're using gold for the black suits, what will you be using for the red suits?
File size errors are common - five graphic files to a post maximum, at not more than 1,000 Kb per file. One-megabyte images are plenty large enough for web page display, but it is annoying to have to reduce image sizes when your file's too big; been there, done that, bought the T-shirt...
For the back design, consider a brighter shade of yellow to provide greater contrast. A low-contrast, mostly-dark design will end up printing like mud if you aren't careful. Also insure that the level of detail you're putting into the design can be accommodated by your printer, because lots of fine detail can also be lost, especially when you factor in that your print surface, likely to be an embossed playing card, isn't entirely 100% flat and level, leaving the chance for distortion in reproducing ultra-fine details.
Black Bart bears a striking resemblance to Mel Gibson! Be careful - if you used a Mel Gibson image to make the card, especially if it was from a movie he appeared in, you could be opening yourself up to cease-and-desist letters from whomever owns the intellectual property you repurposed, unless of course you have permission in writing, which usually costs a hefty chunk of change.
For the King of Clubs and the 8 of Spades, pull back the center image a bit - it's too close to the index. Push the index as far into the corner as you can without getting too close to the die line. Avoid a script font for the index - they're not as easy to read. Perhaps a font resembling the lettering carved into the aft of the ship would look nicer and be more easily read?
Why are you using lines suggesting an aged scroll framed around the king's image while the image itself is a color image closely resembling a modern photo? Pick one style and run with it rather than mashing two incompatible styles together in the hopes that they'll stick to each other. A popular and attractive trend is to leave out frames on the court cards altogether - it allows you to make the art larger and removes the claustrophobic feeling a frame can create.
Is your image really that of "Black Bart?" Or is it just some image of a pirate face you created? If it's the latter, don't bother with the name - the image looks less attractive with the name like that in the first place. It's like putting up a picture of me and calling it "Redbeard." Redbeard the Pirate was a historical figure with a real face, and it certainly isn't my face!
