Please keep in mind that we have a "one question per thread" policy that you agreed to respect when signing up. The policy is valid on the paid help board as well for very valid reasons: if you split your requests into different threads, possible job takers that are up to just one task would be willing to do the job. I doubt that there will be any replies of freelancers who are willing and ready to do all of your requests.
Is there a way to modify the paypal mod
You should post a reference to the actual paypal mod that you want to see changed, as there are several of them.
On another topic: is there a way to have password protected albums? Instead of creating user groups, can I just make a simple password protected album that anyone can view if they have the right password?
Feature already exists in core.
One more thing: is there a way to disable right click and have a pop-up come up that says, copyright protected or something of this sort?
Possible, but silly. Has been discussed in detail already. I recommend just searching the board.
And finally: any way to make an image effects so that the viewer can preview the image in B&W and Sepia.
Easy in Internet Explorer, hard or nearly impossible in all other browsers, unless you're willing to create and store the sepia images separately.
And finally finally: can we make a photo comparison where a user can put 2 photos next to each other so they can compare which one looks better.
Sounds tricky. Easy to display two pics on one page. Hard to come up with a good and easy way to create the navigational elements on the page to allow the user to select them in the first place.
