Regarding Individual photographs total protection is nigh on impossible and furthermore anyone can get the idea and reproduce it themselves. What is more worrying is the actual concept of a particular presentation. I saw PTE in August and after 5 mins I knew I wanted to buy it, It was so good I did. As other people have said is it worth all that hassle to rip off a particular photo? So now and boy am I having trouble all ways. Timing PTE is a real pain, I have been reading all the postings on here and had come to various conclusions myself. One of them being that I had a presentation ready, then I resized all the pics down. The timings went to pot!!! I had saved 10MB of space but of course each image was loading quicker and so it went on and on. Now I have it in synch (manually) and yes on different machines it runs at different speeds, that I expected. I can't work out how to it in the synch window because I need to synch both pic duration and effect duration. (Any ideas most welcome) This is now getting to me as this is a presentation I first did 21 years ago on a 3 slide projector system and I thought at last I can now get it out to a wider audience, and this forum seems to be the best I have ever seen. Now comes the crunch and returns me to my opening response to a previous message. When I first presented my work it was deemed to be worthy of Euorpean worth, now that I have redone it in computer form all the people that I have shown it to say I have to sell it and let lots of people see it. I do want people to see and I am willing to do so, but do I do that on here and risk any strangers ripping off the idea, not that from what I see any in this forum would do that, or do I just say this is for all and let it go? Also it would be nice to earn some money at last. As I said at the start individual pics can be copied or even reproduced but an entire work is a different matter. Discuss Mike
